At least a couple of times I've seen mobs without their limited items but also without an illusionary version. Two ways I think this might be happening:

1. Item is requested. Mob now lacks the item, but also lacks an illusionary version. Seems like after the request it should hold an illusionary version that subsequently becomes "real" when the item would normally have been reloaded on the mob.

2. Item is in mob's inventory and gets stolen, not replaced by illusionary version.

Some other situations I haven't tried but that might be problematic:

* Mob has illusionary item, player gives non-illusionary version of that same item to the mob. Now it has both normal and illusionary versions.

* Illusionary weapons removed by means that move them directly into a player's inventory. Strip, grapple, shield of boiled leather, etc.

>1. Item is requested.

Was fixed awhile ago.

Yes, there are scenarios where an Illusionary item won't be on a mob. An example, mob loads with limited item, someon dirt/disarms. There is no reset for the mob, so it will not load illusionary until someone kills it and it resets.

Not an overly interesting scenario in my opinion.

These were all covered when I put the change in (in theory)
