Compat issue with ULTRACRAFT sliding

(please note that this is a semi-copy-paste from the git from the ultracraft one for issue ultracraft#181 and that i was using Sinytra Connector )

How did i find this bug?

so i was playing around with the ULTRACRAFT mod this mod when i discovered that (with ANY latex tf, yes even the human latex) if you are one of the latexes w/ consciousness, for some reason, the slide will NOT change your height to 1 block.

Also note that the feet paws and some limbs will still do the basic ground movement animation

Again, i will say, if you can give me some tips for debugging this slide height change thing and the animations for it, its appreciated.

(also forgot to put this here, when u get tf'd also doesnt matter if its human latex, the player will not hold the guns with the arm outstreched.
also the nailgun is weirdly posisitoned when holding it. vid here: https://drive.google.com/file/d/1DBdP9PDaBivg2j4LqDRB-JaK6om47CEO/view?usp=sharing )

Beginne damit, das ULTRACRAFT-Transformations- und Rutschverhalten mit Sinytra Connector nachzubilden und die transformierte und untransformierte Bewegung mit den verlinkten Videos zu vergleichen. Untersuche, warum transformierte Spieler keine Rutschhöhe von einem Block erreichen und warum sich Armhaltungen und die Positionierung der Nailgun unterscheiden. Die Aufgabe ist abgeschlossen, wenn Rutschhöhe, Bewegungsanimation, Armhaltung der Waffe und Nailgun-Position während der Transformation korrekt sind.
