Going from 2.11b10b to 2.11b12c the screen tics timing has changed a bit.
I had several screens set to the length of some mp3 sound effects, these all take longer before moving to the next screen, enough that it starts looping the mp3.
The change seems consistant in the added length to the several screens I checked, probably 1 to 1 1/2 seconds, just enough of a change that they'll all have to be adjusted down a bit.
screen tics timing
For some reason this problem seems to have corrected itself over the last 2 days, I checked them today and the timing was right on.:shrug:
This can be removed from the bug list.
I know what was causing this, it's where the first screen tics don't count down right, this was reported in another thread just a few days ago, so at the very least this is a duplicate.
