So I find inconsistencies resetting the build menu once opened with a villager.
WRONG (no reset)
-Select a villager open build menu then deselect villager by clicking ground then select (any) villager again
-Select a villager open build menu then select another villager
WORKING
-Select any other building or unit (not villager) resets the build menu to initial status
EXPECTED
-Deselecting and selecting any other unit/building resets the build menu
Build menu Q dark age selected
Build menu start (default nothing -QWER- is selected)
If you think it’s working as intended let me know and I will delete the report.
