For some reason, GetFormFromFile() isn't returning True when those plugins are active. What's wrong?

You might have to type cast the returned values as booleans:

Bool bIsDLC1PluginLoaded = Game.GetFormFromFile(0x00FF0000, "TheyWontEvenKnow - Dawnguard.esp") as BoolBool bIsDLC2PluginLoaded = Game.GetFormFromFile(0x00FF0000, "TheyWontEvenKnow - Dragonborn.esp") as Bool

Alternatively set the variable types to Form and check if the variables are None. The function returns a value of the type Form so you either need to type cast or assign the returned value to a variable with the same type (Form in this case).

I tried both per your suggestions. No change.

They're both returning None.

Okay, I think I fixed it.

GetFormFromFile() was returning None.

0x00FF0000 referred to records that overrided a record in the main file.

I changed the Form IDs to records that are unique to the plugins.

The trace statements then indicated that the plugins were loaded.

I was just about to post that the FormIDs seemed a bit odd before you posted. The index (first two digits of the FormID, in this case the double zeros after 0x) should have been 01 or higher if the plugins had one or more masters.

Thanks for helping me troubleshoot.

I had this problem with another mod. With that mod, I was just getting a custom game setting from Requiem, so I decided to forgo GetFormFromFile() and discovered that Skyrim doesn't throw a fit if you try to get a game setting that doesn't exist without, for example, Requiem installed.

But I couldn't do that here.
