  @Fullpacki Thanks, what do you mean by spamming delete? By deleting using the "X" or deleting by checking and clicking "Clear Selected"?

  Hmm, I can't spam the 'x' after another, so I can't really replicate the problem but I will take your word for it

  I actually found the problem and replicated it. It's not by spamming 'x' but by drag and dropping 'x' into 'x'. I can fix it easily by disabling drag and drop there. Thanks for the find @Fullpacki

  @Fullpacki @TheRequiem It might be that when you spam click too fast the function handling the cross button is running into race conditions that is competing for access to modify the same data at the same time. I did try to replicate the problem but there wasn't any on my part....or I wasn't fast enough in spamming lol.

  @adityaphasu Hahaha maybe, at least a todo isn't done for spamming delete buttons :D

  @Fullpacki haha for real but while for a project this is okay (and @TheRequiem don't worry about it) in a real life app/web app this is quite a big possibility say a person on a mobile spam clicks the cross button and this happens. This can potentially be categorized as an edge case I think but to solve this you'd have to change the code quite specifically to handle these type of situations 🤖

  Yeah that seems possible, maybe a quick solution can be that I add a slight timeout event and disable the button to give it time and make sure that the users are not able to spam or maybe instead of timeout try to set up a promise for when the state array is done and modified, only then will the 'x' button will be enabled?

  @TheRequiem I thought of the timeout myself and it should be simple fix like if the user tries to click the button again it will only work if like the last one they clicked has done/completed it's operation

  Apparently, it's not because of spamming 'x' but because of drag and dropping 'x' on the same 'x'. I just need to include it to ignore drag and drop in the condition and it should be fine!
