Yea the issue is how bfgminer handles failovers. Currently it assumes that everything its mining is the same coin (this is based from bfgminers original bitcoin origins, it was never designed to handle multiple coins of the same algorithm).

This gets pronounced when your on a multipoool, then have failover/donation configured to Litecoin. This ASIC is different from the Moonlanders and uses a midstate, so the midstate of one coin is injected into another and stuff gets confused.

Sadly bfgminer is starting to show its age, ill see if there is a short term fix, but for now if your on mutipool/rental pool make sure thats the only pool configured.
