v1.0.1 — Bug fixes

OpenChaos v1.0.1 — Bug fixes

Unofficial modernization of Urban Chaos (1999). Requires original game files (Steam/GOG).

A small patch release on top of v1.0.0 — minor fixes, mostly making custom (non-campaign) maps open correctly, plus a couple of other small fixes.

What's new

Custom maps:

• Fixed custom (non-campaign) maps failing to open. This includes maps that ship loose .tga textures instead of a packed bundle — such textures now load and take priority over the bundle (so a custom map's own textures/skins are used). Also fixed opening these maps on Linux (f41b581e, faa6541d, 4dd9db74)

Other fixes:

• Fixed alpha-sorting of semi-transparent environment-mapped surfaces (e6d0fab1)
• Fixed mouse input not working in some cases (reported by PCambraia) (6fd71b5b)
