Constant crashes in landscape mode, path scatter (1.6.0)

Hi, I'm working with path scatter projected on a landscape and I seem to be getting constant crashes in various scenarios. The logs always seem to say the same thing. This crash for example happens when I enter landscape mode.

It seems to be related to the random spin property in the path scatter. Crashes get reduced significantly if it's set to 0 (was set to 45).

I'm not sure 1.6.1 was the hotfix you meant, but I'm just noting that it's still crashing.

yeah it wasn't, that build was sooner created than the fixy for this
