You are dealing with a lurker_hlb3 mod. When you edit his files in the Mission Editor, you've trashed his "schedule" for the RGG. The RGG probably will spawn, but they'll generally be at least 24 hours "late", maybe 25 hours.

You can sometimes "fix" the issue by finding all instances of "DelayMin=" (which have probably been re-set to "DelayMin=60"), and put them at either "DelayMin=0" (zero) or "DelayMin=1", if you don't trust the "zero" figure... You might also check the "MaxInst=" figure, which in most lurker files is set to "MaxInst=1"... but not always... It's always best to work from a copy of the files, and make your own little mod add-in for the corrections. Refer to the original lurker OpMon files for examples and guidance.
