Version history/0.15.0

Version: 0.15.16

Date: 27. 05. 2017

Changes

Temporarily reverted GUI interaction changes (some GUI elements responding only to left mouse button, buttons clicked on mouse up instead of mouse down) introduced in 0.15.13 and 0.15.14.

Bugfixes

Fixed crashes related to clicking different buttons.
As a one-time migration, enemy spawners will reset their absorbed pollution to zero when a save from a previous version of 0.15 is loaded. (more) This is to avoid an extreme temporary spike in difficulty that would happen after loading a save with many spawners that were affected by a bug in the previous versions.
Fixed the market GUI didn't work. (more)
Fixed crash when pollution reaches unreasonably far chunk. (more)
Fixed power bars glitch in electric network statistics dialog. (more)
