It seems that with the migration to Unity 2018.3 our old shaders became incompatible with certain video cards and/or drivers. This caused the game to crash or produce various strange bugs related to visuals. Therefore in 2018.0.6862 hotfix we've recreated all the shaders in the game to make certain they are compatible with the new version of the engine. Our preliminary tests on several different machines show a much stabler behavior, which leads us to believe that the problem has been solved. If, however, you continue to encounter such issues don't hesitate to let us know either here or via email to [email protected] at your earliest convenience.
We wish you a pleasant and trouble-free play.
