[1.1.50] Crash using upgrade planner in multiplayer (EntityPrototype::create)

[mice-stro]

Upgrade planner crashed my game while trying to right click.
i was joined into a multiplayer game and tried to downgrade, outright crashing on my end but not the host.

Thanks for the report. Have you been able to reproduce this crash? Looking into the logic I'm not quite sure what went wrong but being able to reproduce it locally would help a lot.

i have not been able to reproduce this, but my router has been having "first connect" issues. (meaning that the connection is completely stable, but needs 6 or 7 attempts to connect first) would a dropped packet for upgrade planner commands cause this? i know that every game is instanced and then synced, but i read the message on his screen and i only desynced, i wasn't rejected for modified files.
