In the final version 3.4 I added various animations to the UI, such when you add or remove prizes, add or remove levels, etc. In doing so I noticed and fixed a bug with levels, one that probably very rarely if ever occurs: if while the tournament is running you insert a level in your blinds schedule before the current level, you'll effectively change the current level. For example, if you're in round 5 and insert a new round at the top of the schedule (before the first level), the new level moves round 5 "down" one to be round 6, but the tournament will remain at the current position, becoming whatever is before the old round 5 (either round 4 or a break). I fixed this by making sure to increment the level counter. This introduced a new issue. Before, it was always assumed the level counter was at zero when you started the tournament, because a new tournament always starts at zero and the "reset tournament" feature resets the level counter to zero and there's effectively no way to change the level counter unless the tournament is running. So no need to check it when you start the tournament - it's always at zero. But not so with this bug fix. It might have been changed by inserting a new level.
Thanks for reporting this rakrul! The fix will be in version 3.4.3.
