(Did you know there's
the 3.2.5 nightly build?)
But regarding the STAC encoding thing: SCI Companion doesn't re-compress saved resources. Views and such have RLE baked in while others have nothing as a matter of fact, but the resource packs then add a layer of compression on top regardless. Thing is, that's optional and SCI Companion can only
decompress most of the options.
You'd think that's not the issue here and yet I managed to reproduce it.
I should also note that
almost all resources in LSL6 are STAC-compressed, but for example 900.v56 is fine to edit. This suggests to me there might be an issue with the total size of the resource.
Edit: probably not that, considering I simplified the background part of the view by removing all the patterning and then made them thinner to boot but it still messed up the logo...
