Hi, yesterday i have been farming ships of the damned pretty much all day. No problems at all. Today i log in to farm some more, and now suddenly the cannons are damaging the structures on it. I have 9 cannons on the back in rows of 4 and 5 above one another. If i shoot them they damage the ceilings and walls surounding them. This was not the case yesterday Anyone else have this issue?
