This crashes the game for me every time with the latest Aleph One executables on Windows as of the April 8th, 2021 build when I start a new game.
Marathon Infinity.exe for example.
Removing this plugin makes the crash go away. Running with only this plugin makes the game crash.
However, if I download and use AlephOne64.exe then the game will run and not crash.
I don't know what in this particular plugin will create the crash, but I'll submit a bug report for Aleph One on Github.
There were some manual edits done to the fighter shapes to keep their staves/glow maps consistent between frames. The inconsistencies were obvious with the higher definition monsters, so thanks to Aaron for cleaning up the originals.
