CompleteLocationChecks hangs if the socket is closed (or packet send otherwise fails)

[StellatedCUBE]

An exception of type ArchipelagoSocketClosedException is logged from the socket handling thread, however it is not propagated to the thread calling CompleteLocationChecks.

Honestly, the sync functions probably shouldn't block at all; fire and forget seems more reasonable here, since they're likely being called from the main game thread.
