This is a common 'feature' of that editor. It occurs quite often when trying to change/import/edit '.dlv' and '.blv' entries in GAMES.LOD. The 'fix' is both simple and sometimes quite complicated.

I'll do a quick change of the size 'stat' of the Goblin, start a new game tonight and see if it makes any difference. If it does, I'll put together a quick .PDF, picture-oriented 'tutorial' on what to look for using a Hex Editor for changes like this. I assume that you already know how to 'export' the '.bin' file and have a basic understanding of "Hex" (0 --> F) entries.

I'll let ya know via this site, and via email, how it goes.
