i cant disable maps! I force close it but somehow it manage to autostart and runs in the background! I have sign out of latitue, uncheck show location, uncheck everything but maps still took up 59% of my battery 

Did you do a clean wipe before installing the roms. Batista is already clean wipe but i think cognition is not. Try clean wipe and reflash do not restore any apps yet to see if there is any FC. It could be some conflict with apps/data that you restore.

using batista 3.7.5, gmail got fc sometimes, but nvr face fc from tb. u sure ur tb din corrupt? reinstall it back from market la

I do not faced such FC on these rom ( batista only tested till 3.7.4) . But I read that for the newer versions of Titanium - you just need to uninstall it and download a fresh copy from Market ( not using the saved or old apk ) and the FC issues will dissapear

Dont use mobo player, so idea. I only use vital player pro , a video player worth every sen - plays practically all formats I have tested. However this player has a slight bug, can never restore it back thro TB ; so everytime I need to reinstall - maybe is a built in control to avoid piracy

I've run both Batista 3.7.5 and Cog 1.5.1 this week with the latter been running on my phone yesterday, today reverted back to Batista. Both did not gave any FC on TB. Can't comment much on Gmail app coz I removed it together with stock email app before flashing and replaced with K9.

Have you try replacing the Gmail app with Gapps package from CyanogenMOD or download it from market (need market access)?
