Could you post the full log please? I can't tell why this is because of forestry from the crash report.

If this is due to forestry, it's almost definitely something to do with butterflies. But I am suspicious that no forestry code is in the stacktrace. Seems that the reason we have this crash report is VanillaFix (for whatever reason) blames forestry for the crash.
