A short overview about the other changes:
The time check routine for the frozen ones is redone. It was a suggestion from Martigen (thanks). It helps to reduce the CPU time per Iguana.
The Iguana kill quest advancement is corrected.
And here the most important change in this release: A updated Iguana model!!! Now the animations work almost perfectly.
Actually I wanted to wait with this update till the grammar check is done. But because of the potential game breaking bug I release it earlier. If there are no more bugs found the next version is v1.0.
Update Instructions:
Simply copy the new files over the old ones. Check if your load order is still correct and just to be 100% sure wait four days as described in the install instructions.
