I have done no singleplayer testing, so the circumstances to reproduce are somewhat specific.
The bug was encountered on a dedicated server where I am not the host.
Hellfire arrows (probably any "rocket-jump capable" explosive), when fired near the supposedly-static entities within the OOA event (both portals, eternia crystal) caused them to be knocked back, and thus to slide in that direction indefinitely. The crystal, due to having collision and gravity eventually stopped, but the portals did not, rendering the event uncompletable.
I expect that daring to shoot near these entities would not cause them to slide into infinity.
I also recommend this to be tested with all other entities that don't normally take knockback; spiky balls, blazing wheels, pillars, ect.
