But, what is doesn't tell you is that all the upgrades you applied are also removed. So, all the CBills, and especially days spent on getting the upgrade applied are lost. Seems a bit odd to do that since upgrades are applied to the mech, not to anything that can be removed. You can swap out weapons and still get the range an damage boosts.
I ran a test just to make sure that it wasn't because I had multiples of the same chassis in storage. I applied the 15% Speed Tweak upgrade to the Orion ON1-YAJ you can only get from running a quest. So it would be a unique chassis. Moved it to cold storage, Did a jump to the next planet in an industrial sector, and pulled it back. Upgrade was gone. And, this test was done before I installed any mods, so I know it is not a mod glitch.
Good news is that there are a couple of mods in the Steam Workshop and on Nexus which address this. Here is hoping they change this if they ever do another patch. They should at least update the notification.
