I've run into an issue extracting Karbonite. When I click to start extraction my tanks are instantly filled. The repro is: Start extraction (tanks slowly fill) Stop extraction (tanks stop filling) Wait a while (tanks stay where they were) Start extraction (tanks instantly fill) I think the trouble is in ORSX_ModuleResourceExtraction. The lastUpdateTime isn't being changed when the part isn't enabled, so when you re-enable it there's a huge deltaTime from the last time it was stopped. Adding a call to ResetLastUpdateTime() in startResourceExtraction() fixed it for me. If there's a better place to send bugs/fixes, just let me know.
