Should be fixed with version 1.6.2. I added minimum values for the duration property of 1, and it proerly raises those two values on load.
2.681 Script @GTTS/data-final-fixes.lua:195: Object: fallout-explosion Key: duration Value: 0.5 too low clamped to: 1
2.828 Script @GTTS/data-final-fixes.lua:195: Object: tl-empty-smoke Key: duration Value: 0.5 too low clamped to: 1
