System: Windows 10
Game Version: 0.4.5
How to Reproduce: Create a simple battle macro (one or more conditions that direct the creature to attack). Make sure the last line in the macro reads: If this creature has >0% health, defend.
Without exiting the session, assign this macro to one or more creatures in your group, then use it in battle. You will notice creatures with this macro attacking and defending on the same turn. I’ve noticed this happen after editing an existing macro as well.
Note: saving and restarting seems to clear this bug.
