Hi,
right now, after recent Patch (or second recent) I guess, there is a hard delay with error message on server side (?), if you put items fast in the selling frame, for example if do 2x right click on an item in the bag. If you do so, the price will be reset to empty if you had for example "last price".
Can you just change the function how the "get last price" for an item works, that it will get the value from local cache instead of pulling the value from the server? I guess it pulls the value from the server or the issue is loading the price history instantly every time you put an item in the selling frame.
But changing that no error will occur and taking the value from local and just ignore loading history, if you click too fast or accidentally double click. It would improve qol I guess.
Greetings
