Spose I'll mention it in case eyeballs hit the thread.. You can fix your tilt by getting into then back out of the sundy you just spawned at.
Perhaps if I raise this exploit they'll patch it faster: while stuck in the tilted/leaned bug position, it's possible to shoot through walls/spawn shields if you press yourself against that surface. I don't encourage it but feel this needs to be more widely known so the issue can be addressed seriously.
