Did they do any change that affected existing bases?

I had not played for at least a year, maybe more, and I recall having a base by the area where you get the first Chillet, which has ore, and had a second one by the Egyptian looking pal that is very hard to beat, and ofc my first base in the plateau exactly by the start area.

The towers I defeated stayed the same. The humans I captured and the ton of pals I have the same, but I now only have the first base I built by the starting area, the others just vanished, along with all the pals I had working there.
