Thanks, I'm glad you like it so far, and thanks for reviving my WIP thread for once.
Actually you're not the only one encountering this from time to time. It's a reported issue with my scripts not properly cleaning up all string_vars afterwards, which is leading to savegame bloating after some time. I know it's a bad excuse I didn't know you had to clean those up as well back then, as it wasn't mentioned in the docs, but still it's an annoying and by time even game breaking bug I'm dying to fix since it was first reported to me. Unfortunately though script improvements and bugfixes can only take place once I finally got around to buy a new pc and have some free time to actually do it. I officially suspended all my modding projects until further notice a long time ago, but it really hurts to not make any progress anymore for several months.
However, there is a somewhat simple way to fix this, or better yet reset the bloating back to 0 and let it start over with building up again. Just do a clean save the following way:
First you need to change your race to something not coming from my mod. Open the console, type in "showracemenu", close the console (or leave it open all the time), change your race to something non-dragon (without touching any appearance options or anything, as you won't want to alter your appearance, only your race temporarily), open the console again so you are allowed to save your game while the race menu is still open, and then save your game and quit (without ever pressing the done button of the race menu, which would damage your stats and cause several other not-that-obvious issues!).
Next disable my mod and load your new save. This should not complain about missing a plugin for the savegame and you should not get any issues with the race your player is of suddenly gone (you changed it just because of this). Now save your game another time, with my mod not running anymore. This is the clean save, which should be clean of all string_vars or other left-over data junk I forgot to clean up in my scripts. Then quit.
Reactivate my mod again, load your clean save, you should get the initial popup reporting all arrays were initialized successfully again, and the race should be working fine again. Just switch back to your preferred dragon race the same way as the previous time and everything should be back to normal again... or so I hope.
At least this solution was reported to reset loading and saving times back to normal from other users of my mod encountering the same issue.
Yes, the voice set was configured to be a new one of its own, but of course I didn't yet get around to actually create one. Using the Argonian sound set instead should be absolutely fine for now.
No, there is no texture for any other slot than "foot" and "hand". The "foot" texture slot of the race contains the full-body texture (just as with every body mod out there), and the "hand" texture slot contains the detailed wing membrane textures. A custom race created for Robert's Male bodies and TFF female bodies exclusively (as it is right now) does not require any others. Usage of non-fitting items with Vanilla body parts or made for other bodies than these 2 is not recommended and will cause graphical issues. I left the slots not used by any proper body meshes at their defaults, which seems to be Imperial skin textures. So whenever you see Imperial skin on your dragon, you're wearing a wrong item not made for Robert's Male or TFF.
Assigning the full-body texture ("foot") to any of the other slots will not help much, because it's still a wrong mesh in use with a non-fitting texture-map. It doesn't look right having the whole body texture wrapped around your chest or any other body part. In Vanilla there is one seperate texture for every body part, so those body parts are using the whole image space of the respective texture file to wrap around the mesh, while Robert's Male or TFF meshes only use their respective section of the full-body texture.
I can't wait to see it myself either. There's so much already done and so much still only planned, I hate not being able to release/realize it.
But sadly I can't even tell when I will finally be able to go on again... It hurts to make as little progress with my projects as there is in this thread (close to 0 that is)... I miss modding so much already...
