I’ve already reported this on answerhub
Simply put, if you name… say a static mesh component to Leg.L or Leg.R or Toe.L, Toe.M, Toe.R ect
the game will work fine, until you enable replication for those components then the game will kick out clients when you spawn said character.
With this error:
Stably named sub-object not found. Component: [6]TrainingMech_C_0.[28]Leg.L, Actor: TrainingMech_C_0
Simple remove “.” from the name, and now replication will work.
Just trying to save someone else from tearing their perfectly fine game apart for 40+ hours…
This is in 4.19 (for sure) but most likely many other versions…
