In regards of the limitation I totally agree with you. When I read about the limitation in first place I wasn't paying much attention to the additional info (so that the game should break without it). Therefor I went ahead with limiting the round and read about that detail way too late. I also thought a lot about how to make fix that but I wasn't able to come up with a solution. I guess this has to be fully respected in the early planning phase or it is hard/impossible to add it later (specially if you only have a weekend).
Thank you very much for your feedback :-)
