Building on top of a guy appears to trap him.
Progress doesn't save.
You're right, currently we don't have this feature, but working on it!
Got the same bug. Have to wait he get killed by some ennemies.
Yeah, it was the same placement bug. On this update blocks building on top of units, so you will not have to wait for them to die anymore.
This new update prevents placing buildings on top of units and also lets you move buildings that are already placed. Thanks for reporting it.
