Reproducing steps

Setup Details

1. UndertaleModTool version: the issue is with the latest bleeding edge version. the version that works is last modified 2/2/2023
2. Operating system: Edition = Windows 10 Home, Version = 22H2, Installed on = ‎12/‎20/‎2022, OS build = 19045.4291, Experience = Windows Feature Experience Pack 1000.19056.1000.0
3. GameMaker Game: the data.win file is a modified (using the working version of undertalemodtool) version of a game.droid file i extracted from a mobile port of the pizza tower snick demo. https://www.mediafire.com/file/62q70jg349t81a7/Infinite_Tower_of_pizza.win/file

This data.win apparently has no SEQN chunk, meaning it would be from before GMS 2.3 (released 2020) or using some weird version that lacks it. However, the tool is using other metrics to determine that it's likely from version 2.3.2, causing the misalignments. Do you have any idea what version of GameMaker this was really made in, or if your modifications could have anything to do with the Sequences chunk being missing?

nope sorry. what i do know is that i can successfully run the file using the exe runner from the pizza tower snick demo. i believe my editing may have caused this because although i did not save the original file, i found what seems to be the same online and the version i found loads fine. https://thepizzano.itch.io/pizza-tower-mobile-sage-2019 sorry if i wasted your time. is there a way i could repair my file? Edit: is the reason the new version errors out because the detection method changed?

[Jacky720]

2.2.2.302, huh... there's always the option of identifying your changes, re-exporting those assets and code, and re-importing them to the original with a newer version...

Ah, that's interesting. The 2.3.2 detection is evidently because some sprites have an SVersion of 3, which was introduced in GMS 2.3.2 (and I think they're serializing with all the additional flags that implies too). The most likely way I see for that to happen-- might be wrong, in which case I dunno-- is CopySpriteBgFont.csx, which copies the SVersion from an external data file without checking for version compatibility. So you might also be able to re-save the existing modified version if you changed those flags back to 1 in UTMT 0.5.0.0.
