Thanks a lot - we can confirm that the bug is fixed now. Many thanks for your work - and unfortunately we have no bug left to report to you. ;)
Just out of curiosity - do you have any interest to put this fantastic game to other platforms like GOG? From my point of view it is astonishing that there are a lot of games present on all gaming platforms which have not come out of beta state while Rush Trooper is a really captivating experience and from our point of view the best local coop game in that respect (we have tried more than 50) - and it's the game we spent the most time with by far.
