Exception in thread "DynamicEV Thread"
Log: http://paste.ee/p/QkKrl

There is some work still to be done to make a better hash for itemstacks in the mappings, but your crash is not related to EE3. It's actually related to Open Computers by the look of it (look at the ticking tile entity crash)

DynamicEV runs in its own thread, so if it crashes it doesn't affect the main game
