This mod is a fix for the bug described here: https://steamcommunity.com/app/254200/discussions/0/1750106661712081653/
The mod works by removing the gaussian blur effect that is applied when the research window is open which was causing the bug.

Installation:

Extract the .zip file and move the Maverick.Research_Window_Bug_Fix folder into one of the following folders depending upon your
operating system.

3.1 WINDOWS
Users\<user_name>\AppData\Local\ProjectorGames\FortressCraft\Mods
Note: For security reasons related to loading of plugins this is not the same as the save-game
folder which is in LocalLow. This is a change in patch 6.

3.2 LINUX
/home/<user_name>/.config/unity3d/ProjectorGames/FortressCraft/Mods

3.3 MAC
/Users/<user_name>/Library/Application Support/ProjectorGames/FortressCraft/Mods

Once the mod is installed you will need to select it from the “Select Mods” button on the world
select screen.
