Imported files get corrupted (uncompressed U8)

[SY-24]

Some imported TPL files got corrrupted upon importing them into an uncompressed U8 archive from Animal Crossing. The game crashes upon boot and other ARC viewers also cannot render the TPL files anymore.

To reproduce

• open attached msg_win.arc
• expand timg folder
• drag attached winFrm_F_N0.tpl into lowest spot in that folder
• save

Trying to view the ARC in Switch Toolbox, BrawlCrate or Wexos Toolbox will reveal that its now corrupted. The game crashes when trying to load it. After closing and reopening the ARC in WiiExplorer and exporting the TPL back into Windows Explorer, the TPL file can't be viewed by regular TPL editors anymore.
