What works:
0.25.3.28 + 1.25.4.29 (Without append 2)
(July + July)
It will break something in the game if:
1- Update append 1 leaving the game at:
0.25.3.28 + 1.25.4.30 (Without append 2)
(July + August)
2- Update append 1 and apply append 2, leaving the game at:
0.25.3.28 + 1.25.4.30 + 2.25.8.07
(July + August + August)
We need the base version of the game corresponding to August, otherwise it will break the game in some way
Note: Once you combine Append 1 or Append 2 with the base game, there is no way to reverse it. “Patches” for the base version are rarely leaked, so if a new version of the base game is released, you must download and combine everything again. I recommend saving any DLC (Append) you have downloaded.
