[144.3] Thoughts on mechanic mount? Buffstats?

Hi, I'm currently working on mechanic's, i updated some packet structures that caused error 38 on using the mount-buff, but now i'm facing another problem:

When using the mount skill, the sound play's, and a stat effect seems to be applied. However, the mech mount doesn't appear, and no animation at all is played.

Could this be a buffstat problem? (im currently using v142 buffstats from a server that has mech working)
Or am i overlooking something else?

Found it. showMonsterRiding packet structure is (nearly certainly) incorrect. Thanks @chunkarama for helping me.
