how to be short in minecraft more player models mod

This server is highly customized with a lot of extra stuff installed that does not exist in vanilla Minecraft (for example rocket boot flying, warping, setting /home points, setting fake player models, and lots more). I have recorded the replay building a large building on a survival multiplayer server - the biggest German survival server ''.

Java version: Version 8 Update 144 (Build 1.8.0_144-b01) - I am using Java 圆4 for Minecraft and allocating 4096M to Minecraft. Other mods: Worldedit (v1.12), Optifine (v1.12), LunatriusCore & Schematica (both v1.12), LiteLoader (v1.12), Macromod (v1.12). Launcher version: 1.6.73-j (old Minecraft launcher) In the rendered video, I couldn't get it to work at all - I have tried at least ten times. The player models sometimes don't show or don't move in the replay. This time, I have a problem with a pretty long (4:30 hours) multiplayer replay created on a multiplayer server. I feel kinda bad for this is my second bug report within a short time - I don't wanna be the complaining guy! -) Since my last experience with you guys was nothing short of amazing, I will try again, anyway.
