I suspect GuiInterface.GetEntityState() is indirectly triggering some unsynchronized calls to ApplyModifications(). Is there a way to simply not synchronize the cache? (And a getter should probably never modify the simulation state as it's unexpected behavior)

Can reproduce this with the same revision, both running of windows machines (Vista and Win7). Game went out of sync after about ~5 seconds of playtime.

In 11761:

Don't serialize the technology modifications cache. Fixes #1384.
