there is a known bug with this for EFT, SPT as a whole doesn't make this issue worse and I'd hope a mod cant do this either,
you could check if using no mods makes it better but I'm 99% sure it won't if its the bug I think it is.
unless someone else has any insight into this, I'm going to say its the EFT bug and nothing can be done
Okay, thank you for the answer. Have a nice day
