UDB error: "Actor is double defined"

[DamTheGreat]

I recently switched from an old version of GZDB to UDB and suddenly an error pops up. My first custom actor is apparently double defined. I checked the DECORATE lump and nothing is doubled, the editor number is 14166, the sprite is present only once between the sprite markers, the spawn state is defined as "palm a -1". I don't know what could be causing this, it seems pretty minor, because the WAD works fine, still, I want to get rid of the error.

Perhaps you're loadig your mod twice (e.g. once normally and once as a resource).
Maybe there's a doubled #include that causes one file to be loaded twice.

It's hard to say without knowing more.

Ah, that's it! I included it as a resource too. Thanks for helping!

EDIT: Actually no, that wasn't it. I think I'll switch everything from DECORATE to ZScript, that'll probably fix it.

EDIT2: Converted everything to ZScript and the error is gone.
