Platform: Windows 10
Frequency: Currently Unknown (but do I want to find out?)
How to trigger the glitch:
1. Have a character from before the update, preferably a nice, old 2017 one.
2. Log in to the game, and choose a profession, resetting yourself back to level 1.
3. Then, before ANYTHING ELSE: go to the Great Engine in the Town Square and give that thing a tank of Aether!
What happens: I earned 33001 RP, and immediately leveled up to level 2. My stats remained the same on my status screen, despite leveling up. Then, after losing a fight with a group of automations, my page refreshed and I found myself at level 6. Leaving the tower and going back to No-Man's Landing retained the Level 6. In theory, I could just keep on placing Aether in the Engine and keep leveling myself through all of the stats chaos until I get back to ahem my proper level 25, and possibly even beyond. Level 95, anyone? Those autos in the Lagoon will have a time with THAT.
See, Mech, this is precisely what you get for insulting old players by sending us back to level 1 without enough quests to level us back up. The Revenge of the Fuzzywalker is coming for you. MUHAHAHAHA!
Okay, back to sanity.
Why this is probably occurring: When you sent all of the previous players back to level 1, you forgot to reset all of our RP points back to zero. Putting Aether in the great engine is probably a function of how much RP a player actually has, and that dictates the increase. So that program is seeing both the low level and the sky-high RP values and going to chaos. Probably the way to fix this is to actually reset everyone's RP points to zero when they go back to level 1.
I would not, however, remove the Great Engine as a way to get level up points. That's just going to leave us old players up a creek without a paddle fighting autos down in the new areas and frankly everywhere with no way to level up enough to beat them. But we should actually have to work a substantial amount to get our levels back up like all of the other players using our collections of Resistance Posters and access to game areas to gain Aether, rather than having a glitch that could skyrocket us up to level 95. All it would take is 16 Aethermeters to get there at 6 levels per meter, and that's definitely within my reach right now with all of the items I've saved up. In any event, the stats chaos is definitely a glitch.
So I'd appreciate it if you'd fix the glitch, because I want to start legitimately leveling up again.
