In TxDistributionInterceptor.visit(Replace|Remove)Command the ignorePreviousValue flag is set to false on nodes which are not executing the transaction. Usually this does not matter, but when some other node requests transactions from this node (during ST), the Remove and Replace commands are sent with this flag set to false, which results in skipping their execution.

Note: the overall behaviour with ignoring the command when this flag is false and origin is not local seems to me as abusing it - the semantics of the command is far from obvious. When the non-origin node receives the exact command that is executed on the original node (without ignorePreviousValue set to true), it simply ignores it.
