Server instantly crashes while starting if instantScheduling is set to false in carpet.conf

[PentaSteve]

I was messing around with instant scheduling on a creative carpet server, and for some reason I decided to set it to false permanently. Next time the server restarted, in was in an infinite and very rapid crash loop. The only way to fix this was editing carpet.conf

Crash report would be helpful.

Yeah, for some reason I didn't even think to provide a crash report.

Just had this happen as well, same crash report.
Removing the default setting from carpet.conf fixed the issue.
