I have a world that i play with a friend though a gaming VPN service and we have been going fine until recently when we started getting crashes when ever the nanite factory was on. Intitally we thought it was because we were using it to deconstruct a SPRT argentavis we captured but it still had crashes after disabling deconstruction in it's settings.
It only started happening recently and it was working fine until last week with the "stable" 1.144 build that came out on 18/08.
The SE and NCF logs can be found here: https://1drv.ms/f/s!AsnD6_p2IDJxhsUE7WshRUxoXlUlvA
this is also the first world we added upgrades to a nanite factory.
