treeform illusion never seems to work (to others)
 

i remember this bug from red

treeform doesn't always (or ever) display you as a tree to other players

seems to display you as a <your race> model enlarged - though SOMETIMES i have seen people turn into trees (to ME) but THEY only see themselves as a large <your race> model

is this unfixable due to titanium?

Perhaps similar bug, but others don't see you wielding a bow when taking archery shots.

I have seen people in various illusions be a default male human, sunk in the ground up to his forehead, if I zone in after they cast the illusion. sad

Minor illusions have been broken on p99 for a few years, probably fairly low on the priority list though.

this is likely due to a tree model not being a global model, thus it depends on the zone having tree models (and from my experience using Illusion: Treeform on Enchanter, it uses a tree model from the zone you're in)

From what I understand global models are controlled by the version of the client and so there's no way to add or remove them (which is probably why since it's the titanium client there are many global models from eras much later than velious, as evidenced by GMs occasionally changing to them during events)
