Disable Timers

A new War of the Chosen compatible version of this mod is available here:
http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=1125412463

Disables the vanilla game mission timer in most non-story missions. Notable exceptions are UFO and terror missions.
As this removes a big element of the game, you may want to crank up the difficulty a notch to compensate.
This mod does not disable achievements.

If you stumble upon any bugs or missions types that I've missed, please report them in the comments below.

A campaign reset should not be neccessary, but it is recommended. If you decide not to restart, it's a good idea to back up your save before you enable this mod.
You can find your saves at C:\Users\ Profile name \Documents\my games\XCOM2\XComGame\SaveData
Once you save your game with this mod enabled, it will no longer be possible to load the save without it.
