Assertion failed! Invalid Spine cache format version number

[hacpark]

Describe the bug

When I try to unpack data.win to modify a game, the above error occurs.

Reproducing steps

1. Open data.win with UndertaleModTool
2. Loading fails with the load error

Setup Details

1. UndertaleModTool v0.5.1.0
2. Windows 10
3. The game was released on September 28, 2023. I'm afraid to link or upload the game directly because it contains inappropriate elements. Sorry.

Hi,

I got your email. From what I can see this doesn't seem to be related to Spine directly, rather something else broke which is causing ModTool to falsely assume that a sprite is using Spine. Can you email me a link to the data.win file? I don't need any sounds or executables. Otherwise I won't have any file I can work on to actually fix your issue. I live in Russia so any inappropriate elements are not really a concern here, since nobody cares.

Got the file via email, will take a look later.

@nkrapivin did you ever have a look at this?
