Crash with MainStage 3

[jkndrkn]

Hi there, I am running MainStage 3 on a macOS 10.13.1 system. I keep getting a crash when recording a second loop that is synced to a parent loop, but it seems to happen most often when overdubbing that second loop. I have attached a screenshot of the settings I am using.

Here is a gist of the crash report: https://gist.github.com/jkndrkn/dda0172 ... 0b7000e522

Thanks for your help with this!
