V123.4SE released.
check IsBlockingServer for data sync logging (clee's idea recently, xytrix's idea 11 months ago) - Joy said he would test for it in the next HR but I have no idea if it will fix the data sync problem until it's out, logging shows a correlation though.

ps. I have gotten 0 logs related to kara cards and few complaints about them at all. Considering that I wrote most of the code for them before they were available and I just found a broken sim myself, there is likely more problems with them. If there are kara cards that you want to be using, TRY THEM OUT, and report any obvious misplays with them.
