Erosion Seed Port Connecting causes Crash

World Machine crashes when connecting the Erosion Device’s seed port to a Macro Parameter (Integer and Scalar tested), and can crash when connecting a scalar generator (device). Device version doesn’t seem to matter.

Also had this today, without the crash but with endless livelock (all cores 100%, ui locked up, forever)

What worked for me: Set the parameter to something other than zero before connecting it to erosion.

Something about a zero seed causing problems?

Tried that as well, however, it would then crash later on regardless.

It looks like a value of zero for the seed is causing the issue. I’ll make sure this is fixed in the next version.
