Sorry for a late reply there... I seem to have missed this thread! (O.o)
Ahm, you say you can't save your games for either of the Rebuild games? It might sound silly, but you are certain that you are logged into ArmorGames when playing them, right? And you are not switching computers, because this will affect your save games as well as they are localised on your computer. To be completely sure, check if your computer accepts the save game data from ArmorGames, ok?
Let me know if this is all in check or whether it still causes problems for you! =)
I am having the same problem for rebuild 2. I am logged on my account, using the same computer, and accepts saving game data for other games on armorgames. what else can be done?
Just played a little Rebuild 2. The game saved just fine for me. Both the auto-save AND the manual save found under settings in the upper left corner. Looks to only be 2 reported problems... and that seems more likely to be issues specific to them and their computers than to the game.
I don't think that they save onto your AG account, so it's probably a problem with your browser/computer deleting the cookies/caches used to save the game's data. Try checking your settings by typing aboutreferences#privacy in the main search bar or going to preferences and then the privacy tab. @Brainslug
