I was playing Wargroove with my brother in Nintendo Switch with the Spanish version, while playing we wanted to try the ballista and the trebuchet and reading the description (in Spanish) it said that it could attack and move in the same turn, but when we tried it we couldn't. Later that day I checked out the English version and it says unable, just the oposite. I think this should be solved because it is very confusing. I will attach an image of the Spanish version so you can see it yourself. Hope this helps!
