Heyho,
I could only produce this bug once, but I will fill you in on the details regardless. If I can get it reproduced consistently, I will update this post or create a new one.
1. Description
The User Interface for the cv is mostly gone. All thats left is the message: press f to return to the carrier
2. Reproduction steps
I played my Ryujo in a Tier 8 matchmaking. Took my torpedo squad through the AA of 3 ship to strike an Alabama/Massachusets/NC. The squad was obliterated and while I was still striking, I spammed F to return to the ship as soon as the planes were gone.
3. Result
The UI did not update to the carrier nor the planes that I would select after that. While I could still see the aiming circle, I could no longer see any consumables nor the speed of my planes or ship. I could still use them, but they were not visible to me. I could barely see the health of my planes that was beneath the return to carrier message.
An interesting note here is that later on, this bug fixed itself. But many people would have probably quit the game by that time.
4. Expected result
The planes get destroyed and the player can return to the carrier with his UI updated.
5. Technical details
I missed the opportunity to take a screenshot, but the game runs on the highest settings on a Windows 10 PC.
Also, I dont know why, but there are some framerate issues with the game at points, even though they were not present before the update.
Graphics Card is Nvidia GTX 1060
Ram 16gb
Intel i7 8k series processor with 4+ ghz
