Invalid app vault doesn't work after updating launcher

[SantiPT]

So whenever I update the system launcher to a more recent one in a xiaomi.eu rom the app vault stops working, I can't open it from swiping to the right, or by clicking "widgets", if I click the widgets icon, instead of the app vault widgets showing up (the xiaomi widgets) the stock android widgets page (the one you see on global rom) shows up, updating the app vault to the version that is provided from the same china rom version where the system launcher apk got extracted from does not fix this issue, example (if in a more recent china rom app vault is on version X and system launcher is on version Y, and I install both those versions on that were extracted of the china rom in a xiaomi.eu rom the app vault still doesn't work), what I verified is that updating the launcher in china rom does not make app vault stop working no matter the version of system launcher and app vault.

Does this have something with the xiaomi.eu patches you guys make? How can I make app vault work on a more recent system launcher version that comes from a china rom?

You are not supposed to update the system applications in the Xiaomi.eu ROM

I'm aware, but the new system launcher has smoother and stabler animations, on top of that it lets me set the grid to 4x6.

It doesn't matter. You are NOT supposed to update system launcher (and any other Xiaomi's system APK in our ROM).
Official system launcher tries to find Global App vault. We use Chinese App vault.

Even the Chinese system launcher looks for the global app vault?

System launcher is same in both Global and China ROMs, so... yes.
