There's nothing wrong with the actual mod so something happened to the PAMM repository. Looks like it was removed from PAMM or something... STUARTTTTTTTTT
Well something is wrong with PAMM for your mod, something that only the github users can fix. And also I'm getting the error "Failed to load modlist data: Service Unavailable..." when trying to view available mods, are you getting that too?
Your problems updating the mod were because Gandalf strangely changed the identifier at some point. Don't do that Gandalf, it causes problems.
LOL Edit: Oh I just now realized that it actually lists all the mods which have a corresponding lobby up. Haven't noticed that before. I thought Gumma Gumma was... special!
The last 3 or so server mods used are shown in the drop down. If I go name a game right now then "Secret Mod" will be displayed at the top.
I had the exact same moment, thought kiwi had hacked the game code or summin. Also... I love this mod <3
1.3 of GGS is up on PAMM, we added 2 new custom particle effects for commander landing and commander basic weapon. Made the commander and the Guma select in the same selection box.
This mod has been included in the eXodus eSports Planetary Annihilation Mods - New Year's Mod Picks guide.
