Description
Ships disappear from fleet manager

Game Version
Shelley v2.5.1

What version do you use?

Steam

What expansions do you have installed?
All of the above

Do you have mods enabled?
No

Please explain your issue is in as much detail as possible.
Some ships disappear from the Fleet Manager. Once they disappear they can no longer be managed, splitting or merging the fleet does not fix the issue, issuing an upgrade order does not fix the issue.

Steps to reproduce the issue.
- Start a New Game
- Create new ship designs and discard the default ones
- Split initial fleet into individual ships
- Assign different designs to each ship
- Merge the fleets back
- Counter will show as zero, ships still exist but will not show on Fleet Manager ever again, see attached screenshots.

Any update about this specific bug? It still keeps happening, but worse since last patch, as it is clogging the fleet manager with invisible ships that have "-1 remaining building time". This eventually renders all shipyards useless, which is game-breaking.

Started to experience this problem on 2018, reported it in 2019, almost end of 2020 and still not looked into.

What about fixing the game before adding new content? This can be game-breaking in certain situations.
I would like to play the game, not just stare at it in my Steam Library missing the times when it worked.

If we take into account both the content I purchased for myself, plus the one I purchased for my friends to play together in order to support this altogether it almost adds up to 400€ invested in you with Stellaris only! Paradox, I understand that development is a busy matter, but can you at least provide some sort of response or attempt in fixing this in a time frame smaller than 2 years?

I used to be a very content customer, I just want to be able to at least use what I already paid for, please tell me. What happened there?

Edit (01/14/2021): I have just noticed there were attempts to fix this as per 2.8 patch notes. Issue still happens, but I see there was work put into it
Fixed completed construction items for reinforcements not being removed properly from the fleet manager.
