Kingsmarch mappers bug possibly related to kidnapping and adding maps in the current session

Last night I collected the rewards from 5 maps from each map device, then I added another 5 maps to each map device while the mappers were still running before logging out

Today after logging in I find that in one map device, one mapper was kidnapped exactly before the last 5 maps which is already a weird coincidence. But the other 2 map devices also stopped running, exactly on the last 5 maps that I added

Kingsmarch had 200k gold left so it's not gold

Got same problem, but after i pay 50k for release from kidnapping
