I'd just like to post to recommend that:
a) you only update IG_Battlegrounds to 1.150 once the ENL Admin mod has been released for that version (or for the version of whatever hotfix is presumably incoming) and
b) you keep the Native glitch-free ENL maps rather than updating to the new Port Assault for instance, until the end of this ENL cycle. The old maps are being used until the end of the ENL cycle presumably because people are still more prepared on the old maps (would be a bit lame if a match like IG v.s. Trinity, RNGD v.s. Trinity w/e took place on the new Port Assault without either team having really prepared for it). I think the same argument essentially applies, clans use Battlegrounds to train competitively, and it's less useful if you're using a radically different map to the one you'll actually be playing matches on.
