Commandoes taking a very long time to build landing zones

It took a commando ~3 min to go from 0% to 1% building completion. This was in svn 1704.

They likely lost their builder tags in one of the pytdf runs. Easy fix, thanks tot.

It resulted from the buildtime normalization; I didn’t realize that commandoes built both satchel charges and LZs. I’ll tweak workertime/buildTimes to fix it.
