There is a new patch out: 19.7.56
http://www.ootpdevelopments.com/board/s ... p?t=290862
This one is particularly a pain, because it is not compatible with our current patch, for online leagues. (Says so on the site, and the PCBL already has one GM with an issue exporting.)
Steam has apparently already updated, pushing us to move much more quickly than usual.
Tomorrow morning's sim will be post-patch. If you have already exported pre-patch, you should be fine, I am doing imports in a few minutes. But if you have not yet exported, you should patch prior to exporting.
