[2022] Something here isn't right. UPDATED ( remove all mods )

Please contact Customer Support about this. I've seen one other person mention issues trying to buy a Tech Tree ship.

This is strange indeed - please do write a CS ticket about this and include your screenshot and a detailed list of the problems.
They will help you straighten out something like this

Small follow-up. The other thread reporting this issue is here: https://forum.worldofwarships.com/topic/257180-buy-button-broken/

It was suggested to the OP that they disable Mods. If you have any Mods active, please try removing them and see if the issue persists.

Please let me know if you figure out which one seemed to be at issue.
