disabling enhanced models still load and inspect md5 files and crash in MG3

[j4reporting]

new remaster update 2026, mod gamedir mg3 map map1.bsp

disable enhanced models and try to load map1 of new released episode mg3

./vkquake -basedir rerelease-2026 -game mg3 +r_enhancedmodels 0 +map map1

will crash engine with the same error as with enabled enhanced models.

in both cases engine crashes with

QUAKE ERROR: progs/ogre_rocket.md5anim has incorrect joint count

[Perlence]

Until fixed, the quick workaround is to also set r_allow_replacement_md5models 0.

Another quick workaround is to skip loading the MD5 model when this specific error occurs.

ah some cvar_none.
I checked only the cfg file and assumed this would at least ignore any errors with enhanced models.

maybe r_enhancedmodels 0 should also imply r_allow_replacement_md5models 0 automatically :)
