What is wrong with these PNGs?

[SPZ1]

I used SPZ Archive Tool to make some PNG sprite offsets. What happened is that GZDoom said, "Invalid data encountered for texture OTHER.wad:BLUDB0". I checked the files and some source code leading me to believe there is probably just a stray zero somewhere. Since the sprites still work I'll continue to use them in my project...

Have you tried to correct offsets in slade?

I am not getting any errors when booting up a wad with those sprites and they do appear ingame.
I presume whatever was wrong with them has been fixed when you uploaded them here, so try to download them and put them into your project.

(The only non standard software used here is spz's personal offsetting software, so if I was SPZ, I would try to find what he did wrong during writing that software. It obviously screws up images instead of adding offsets to them)

Sorry guys... I was working with some files and now I cannot seem to reproduce the problem!
