Today my client completely froze when someone deployed an l-mine. This has never occurred to me on this setup before.

happens to me all the damn time...

The obvious, unanswered question here is: Does this happen with no plugins installed?

Doesn't happen to me.... So this is clearly related to all the new fluff in your voce version.

Yeah this happens to me when hit by lots of gatling/popcorn fire. I've had it freeze up the Android client entirely to the point where the OS was going to close it for being non-responsive. (Even w/o plugins)

But yeah, get rid of plugins and try it again. Especially ones that register the PLAYER_GOT_HIT event...
