[MIRROR] [no gbp] Fixes runtime in SSstation [MDB IGNORE] (#22791)

* [no gbp] Fixes runtime in SSstation (#77231)

No excuse, just dumb. Random layer is the randomly generated parallax
layer, which is null 30% of the time, so this would runtime in SSstation
setup in 30% of rounds

Also another thing where I added extra params and didn't add them to the
proc, fucking parallax for some roundstart clients and latejoins

🆑
fix: fixes a runtime in SSstation setup
fix: fixes parallax not rendering correctly for latejoins
