⁠ Certain Anomaly psychic rituals not working in multiplayer ⁠

[jcs-png]

Description
When performing the Draw Animals, Void Provocation or Draw Shamblers psychic rituals in multiplayer, the ritual completes (bioferrite is consumed, cooldown is applied) but nothing ever spawns on the map. Notification appears but nothing happens. Draw Fleshbeasts works correctly.

Have not tested other rituals, but these have been tested multiple times.

Steps to reproduce
1.⁠ ⁠Host a multiplayer session with at least one other player
2.⁠ ⁠Research and perform the Draw Animals or Draw Shamblers ritual
3.⁠ ⁠Ritual animation completes, bioferrite is consumed, cooldown begins
4.⁠ ⁠Notification appears appears, nothing spawns on the map

Expected behaviour
Animals or shamblers should spawn on the map after the ritual completes.

Actual behaviour
Nothing spawns. The ritual silently fails.

RimWorld version: 1.6.4633 rev1269

Multiplayer mod version: v0.11.0tacb33a2
I'm aware there is a newer version of the multiplayer mod available but it is currently not working on Mac, so we are running an older version.
NOTE: Latest v0.11.4 does NOT work at all on Mac

Note: These rituals were also tested and confirmed not working prior to the installation of Alpha Animals, Alpha Mechs, and Hospitality, ruling these out as potential causes.

Additional finding:
When switching to async time mode, all previously failed psychic rituals trigger simultaneously on save load. This backlog then re-triggers every time the save is loaded in async mode, even when the events from the previous load are still active on the map.

This is repeatable and consistent.

For further testing, converted the save to singleplayer and removed the multiplayer mod. All rituals perform as expected in singleplayer, confirming the issue is specific to the multiplayer mod.
