Whenever I have a mekanism flamethrower set to inferno and start burning down forests, I crash. This only happens when I aim it at certain BOP dynamic trees such as a redwood and fir (redwood is the most easily reproducible).

If you need more info let me know.

Alright so apparently the real issue is the game doesn't like it when you burn some trees which also include vanilla dynamic trees so not just this addon. I've reopened the issue there and will just close it here.
