delta v losses not equal to acceleration

Thanks for the video and the explanation! Now I understand and I can reproduce the issue at the office. I'll see what I can do to fix this issue.

Ok, my phone runs it at 57- 60 FPS if I don’t limit it. Yes it loses 50m/s every second. It does that only once the mass locks up. One question, is this caused by me running in the beta version? I’m buying the game in the next week, will that fix it?

Here’s a clip with the moment it stops losing mass @AndrewGarrison

Now I'm confused what bug you are reporting. Are you referring to Craft Mass under Performance in the flight inspector window? It is dropping for me as I burn fuel.

Back to the original issue with delta-V dropping too fast, can you answer the question: Over how long a period of time? Are you saying that it is losing 50m/s of delta-V per second?

How many FPS are you getting with this craft? 127 engines is quite a lot and could cause low FPS on a mobile device.

I have found the issue by flying the craft and paying close attention, the fuel continues to burn yet the weight stays the same at a seemingly random time during flight @AndrewGarrison I hope you find a fix because I’m quite annoyed at this bug

Over how long a period of time did you run the experiment? Are you saying that it is losing 50m/s of delta-V per second?
