That way if someone's in a wheelchair or riding a taur they will not be pulled out of the inside of wherever they are when the thing they're buckled to moves.
Allows morphs a couple of neat new things
Resting:
While resting and morphed, morphs do not 'look strange'.
If a morph stops resting while someone is on their turf, they may instantly, stealthily eat the person. (If prefs allow)
Take over prey:
A morph may choose to attempt to completely take over their prey's form, actually assuming control of their prey's body.
This interaction allows the morph to pick any non-simple mob in any of their bellies that has a ckey. The morph gets a confirmation prompt, and the prey gets a double confirmation prompt. The prompt can only appear if the prey has the preference for allowing body impersonation enabled.
For lack of an easy better option, this interaction is undone by way of the transformed morph ejecting the prey from their belly. Instead of actually ejecting the prey, it will restore both to their original conditions. (And THEN you can eject them if that's what you want to do) There is text explaining this to the morph when they succeed at the takeover.
OOC escape does also work with this, despite its complicated interaction. OOC escape returns both parties to their original bodies and undoes the effects of the interaction.
Fixes a space vine runtime
Makes it so space vines can't climb stairs (because that leads to practically unkillable stacks of vines that lag the server)
Makes it so space vines can't grow on open space (because you usually can't kill vines if they're way out in open space and that doesn't make much sense anyway.)
Attempts to limit the maximum range of plant bioluminescence (having hundreds or thousands of dynamic light sources with maximum possible light range seems to lag the server)
Adds a funny dog that no one should ever actually spawn but I will one day as a joke and everyone will cry. (its base form is actually not hostile so if you kill that one the hell you earn will all be on you)
