Milestone 4.11.0 Released! (Experimental)

[Chris]

This update is also only accessible by switching to our Experimental branches (instructions on how to do so here) - although please be aware they have slower load times and worse performance than normal builds due to the extra logging they contain!

Fixes & Changes:

• Added research text for the Alien Psi-Amp project.
• Added updated translations for the various non-English languages.
• Fixed a crash that could occur at random on the Geoscape when UFOs were flying around.
• Fixed a crash that could occur when starting air combat.
• Disabled various doors from autoclosing (UFO doors, alien base doors, blast doors in Xenonaut / Cleaner bases) as a temporary fix for the issue where the visual open / closed state of doors gets out of sync with their actual open / closed state.
