Original [issue|https://support.ludiq.io/communities/5/topics/4874-2a10-connection-to-bolt-typed-port-breaks-periodically] - Pending Review

----

This connection breaks after each Unity restart since alpha 7 or so. This, however, is not the original graph, I recreated it from 0 in a fresh project so it seems reproducible and should be present in the project I linked in Discord.

Connection can be fixed by rewiring it.
