Bad V_DrawPatch while opening my WAD

[TheNerdTurtle2]

So I've been working on a WAD for about 2 months or whatever and it's supposed to be 100% compatible with Chocolate Doom, however, today I tested it and before the titlepic showed up Chocolate crashes and left me this message:
Bad V_DrawPatch

What do I do?

Put V_DrawPatch to Google and you will get several relevant discussions describing the possible problems and solutions.

A sprite is too big.

I searched google before I came here, and I will look for a sprite that is too large

SOLVED: I deleted the Titlepic because it was too big but it didn't fix the problem so I was going insane but then I realized I was editing the wrong version of the WAD. I fixed it shortly afterwards haha
