TimeLeftExtender.amxx is in direct conflict with galileo.amxx. What was reason for ;admin.amxx? Also any of your plugins that involve naming or renaming player's names try quarantining them to run on only 1 or 2 maps with an ini file within amxmodx/configs/maps.
The 2015 remake of Galileo points to disable timeleft also.
Brad's version hasn't been touched by him since 2009. I also noticed the same conflicts like why the hell is my server crashing over timeleft? Original version does not tell anybody about that disabling timeleft.
