Whenever I try to open a file in WhackEd, it crashes with the following error:

This does not happen when I create a new file or open a file without an accompanying .WHACKED file, only when opening lone .DEHs or .BEXes or the like.

EDIT: Actually, it does happen when opening some files with .WHACKEDs. I'm currently looking into it further.

EDIT 2: Of all the DeHackEd patches I have, the only one afflicted by the bug is accpstl.deh, available on Doomworld. m8f-text.deh is also bugged, but by a different error:

This might be a mistake on m8f's part. I'm fairly new to DeHackEd, however, so I doubt myself on that last statement very much.
