Attempting to play Zen Dynamics will result in a crash complaining about a 0 tic loop in the decorate code. This kind of behaviour should be revoked because its more annoying then helpful, and the wad works fine anyway.

Fixed. Even though ending state block with

Goto Somewhere
Loop

doesn't make much sense.

Something like that can't be done. This, however, can.

Goto something
null A 0
Loop

The state jumps in Zen Dynamics help its reloading system. There a few 0 tic loops, but they are never reached because of all the state jumps.

It can, and that's exactly what Zen Dynamics is doing (check DECORATE lines 665-666).

Well its always-worked fine in zdoom, so as long as you ported decorate right, there will never be a problem. Can you download VaVoom svn builds anywhere? Or are they all internal and un-compiled.

No, currently I don't provide SVN builds.
