This is just sort of a blanket reply:
Since the three of you are having unique issues that haven't come up before, the installation instructions for new-comers or ROM-switchers need to be followed verbatim, and always make sure that the MD5 sum is verified, /cache and dalvik-cache are wiped, /system is wiped, and /data is wiped. Flash the ROM, then run Fix Permissions. Otherwise, try changing your CPU clock speed and/or the governor. Most or all of the problems the three of you run into sound as though either an app is causing the problem, the ROM corrupted on downloaded, or not all of the necessary steps were followed for installation. And, sometimes, not even the proper method for restoring data post-ROM switch will work (it isn't foolproof, but compared to the near-zero percent chance of TiB working post-ROM switch, it's a much better chance). If you're switching from CM to Sleipnir, or vice versa, I suggest doing a Factory Reset because it's likely that, giving the different Android versions that the /data partition existed on/within, retaining it is likely going to cause problems.
If all of this has been done and the problems are still coming up, let me know. As far as I can tell though, no one else seems to have run into these problems - and the ROM's current build has been downloaded a combined number of 169 times, with only three instances of problems reported so far. If I can solve those bugs, I would love to!
