Thank you for report but it's not a bug. All vehicles spawn with 1 hitpoint when changing chassis

Having a look back at previous gameplay videos it is clear this is a bug.

In this video a new chassis is equipped, and it has 100% health.

If it's a change in functionality - that's fine,

Playing the latest build https://youtu.be/yZmkYrMCjr4 It is true of any combination of vehicle whether you are swapping or placing on an empty slot.

As a primarily solo player I will put forward a suggestion to revert it to the previous way it worked, as the penalty of arming and refueling was sufficient when it came to waiting times.

Yes, it was changed almost a year ago. To prevent instant repair exploit.

Can't you simply remember the repair status of vehicles, so that you are not penalising players? It seems rough. I have not noticed it until now, so I very much doubt it has been in for a year.

If you stored the damage -

Then when the player grabs a chassis it just grabs the one with the least/no damage.

This is what a real motor pool would do when swapping.

If you discard one (because we can no longer send them back to the warehouse) it just throws out the most damaged one.

You can close this. I'll move my comments over to the feature request.
