I've been playing with old dehacked patches and found out that the values set in dehinfo.txt for actors as default heights aren't correct, it seems you extracted the values from Dehacked itself, but some of them aren't right, if you want, please download and test batman doom before and after applying the patch, you will notice that you can walk over the trash dumps in the first map and other decorations, since their heights aren't set correctly.

That's a Vavoom feature. The only way to fix it is to disable walking over/under other things using compat_nopassover.
