* Give Rust Removal a shorter Doafter (#770)
* Yeah, yeah, mircobalance. Every janitor player will fight you though. Welding and brushing walls free of rust now takes just three seconds.
* Now reinforced walls take a bit longer to de-rust. Times are as follows:
Solid wall: 1s weld, 3s brush
Reinforced wall: 2s weld, 3s brush
* Actually, just make both take 4s to brush and 1s to weld. Problem solved.
* changed the welding timer from 1 to 2 seconds for lag compensation.
