I really am not sure how this can happen but ever since the unidentified object exploded out on day 117, thunderstorm keeps happening for 7 days in a row and I have out of food to keep my colony up and running. The exploded object just keeps flashing badly so that my PC lags a lot even it is i7 8GB 560ti. Any idea for me? Thanks!
Found out solution by myself. Updated BetterPower+ mod but it was still doing it. I looked up some error message again before the object exploded then it was telling about a thing named EnginePart3824513 so I deleted that thing from my save file

and that solved out the issue.
