Perhaps it has, but this is not the fault of my mod as the particle being ticked is not from MTS. It is:

Rotating Particle: ParticleTexLeafColor, Pos (-33.06543562095091,40.0,-28.546716809310283), RGBA (0.5098347,0.26402155,0.059177242,1.0), Age 90
	Particle Type: TERRAIN_TEXTURE

The last mod in the stack trace is this one:
buildcraft.builders.BCBuildersEventDist.onGetCollisionBoxesForQuarry(BCBuildersEventDist.java:78)

I would get with them about this crash.
