Getting a Invaild Tileset Reference

[megamarc]

Without having your artwork and the contents of the line you have changed, I can't tell the problem. However my guess is that you've produced 32-bit ARGB artwork, whereas Tilengine requires 8-bit indexed color format, and it's refusing to load it. It's a common mistake. Make sure your PNGs are 8-bit and index 0 is the transparent color.

The python binding is a bit outdated, but the core library got a TLN_SetLogLevel() function in release 2.10 to print this kind of errors to the standard output before they crash something.

Thanks and goog luck!
