Hi! Sorry for the trouble, this is a bug and we'll be fixing it next time we release a patch. However, with the holidays season in Europe, the next patch will unfortunately take a slightly longer time to arrive.
Originally posted by Grogbro: These same thing happened on three different ships from the Workshop. I tried it with large, med, sm ships and same thing, on three different campaigns, maybe 4.
If an issue happens with a Workshop sub, please give us a link or the sub file, as it is possible there is something going on with the sub that causes it. Or, even if the issue didn't originate with the custom sub, it could reveal something we can do better to allow for sub builders to build with maximum flexibility!
