   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.

   I've tested this on new games and it is the same.

   Is this just a mac issue?
   As it essentially makes the Entire Anomaly DLC unplayable in multiplayer as you cannot progress through it.

   Empty their pockets before they hold the bioferrite, it's a bug in Anomaly DLC Ludeon promised to fix.

   Aside from that, it works fine for me. All of them work.

   @notfood when you say “empty their pockets”, do you mean fully empty their inventory or just utility items like medicine / food / drugs?

   And does that need to be the pawn carrying the bioferrite and performing the ritual?

   Just checking whether that reliably makes rituals like Draw Shamblers / Void Provocation actually fire in multiplayer.

   I’ve not seen this workaround mentioned in the GitHub issues or release notes, so if you’ve tested it successfully, any extra detail would be really helpful.

   Yeah, just their medicine/food/drug and if you're using mods to carry weapons, that too.

   

   I made a patch that solves this issue but I'm unsure if I should push it.

   /**
    * Method is missing a break in the second foreach loop
    * Original errors if pawn has anything in their inventory
    */
   [HarmonyPatch(typeof(PsychicRitualToil_InvokeHorax), nameof(PsychicRitualToil_InvokeHorax.HoldRequiredOfferings))]
   static class PsychicRitualToil_InvokeHorax_Fix
   {
       static IEnumerable<CodeInstruction> Transpiler(IEnumerable<CodeInstruction> insts)
       {
           var target = AccessTools.Method(typeof(ThingOwner), nameof(ThingOwner.TryTransferToContainer),
               [typeof(Thing), typeof(ThingOwner), typeof(int), typeof(bool)]);
   
           var codes = insts.ToList();
   
           for (var i = 0; i < codes.Count; i++)
           {
               if (codes[i].operand is MethodInfo method && method == target)
               {
                   yield return codes[i];
   
                   i++;
   
                   yield return codes[i];
   
                   if (insts.First(i => i.opcode == OpCodes.Leave_S).operand is Label label)
                   {
                       yield return new CodeInstruction(OpCodes.Br_S, label);
                   }
               }
               else
               {
                   yield return codes[i];
               }
           }
       }
   }
