As for the push issue, I realize my clip hotfix wouldn't have worked at all as the balls bump off clip walls, too. I made the trigger volumes a bit bigger now, 16 units wide (and also replaced the non-QRP textures except for metal4_2b). Though I'm sceptical the wider triggers will solve the issue (which I believe to be related to either some network protocol/ping thing, or some maxfps-type of config messing). Anyway, might be worth a try:
Edit: As an afterthought, could it be related to that issue where a trigger_hurt in a space map doesn't kill a player if it has fired shortly before (by another player)? So in this case, if two players touch the push at the same time. Clutching at straws here obviously.
