For some reason during my game i was prompted several times even when i had passed to do conversions, which goes against the rulebook stating that i can only convert during my turn.
Im posting here since i only played a single game and cant file bugs yet.In addition to your action, you may freely convert resources
on your tum.
You may do this as often as you like before and/or after your
action.
You can't convert resources any other way, and you can only
convert resources on your own turn.
