Well, Sunday 15th - 15:00 GMT?
Actually, all the bugs reported from the VU-TRC clanwar have been fixed just a few days after the clanwar. I'd recomend CTF5 seeing as CTF4 has some serious balance critical bugs. It would probably be a good idea to have 1 or 2 matches in CTF5 before just to make sure though since there hasn't been much testing on CTF5 for quite a while
