As a temp fix I wonder if it's possible for us to make sure that we never set the limbo player's groups to Collections#emptyList. I think that would entail changing LimboServiceHelper (L46) and LimboPlayerDeserializer#getLimboGroups to use something like new ArrayList<>() instead.

Surprising that Gson needs to access internal stuff when it knows it's a structure but I don't know anything about its inner workings.

Edit: And to be on the safe side the method I mentioned in LimboPlayerDeserializer probably also shouldn't use Collections#singletonList.

Apologies for not being able to test myself at the moment but if someone of you encountering the issue want to try with build n. 2500 or above from https://ci.codemc.io/job/AuthMe/job/AuthMeReloaded/ it would be great if you could do so and report your findings. If the reason for the bug is what I believe it is, it should be fixed.

@smario82 @WongIong please try again with the latest dev build
