I canceled a request for my crabs to be rented out. I wanted to breed them. However, I was unable to complete the transaction. I was unaware that there was an invisible cooldown timer. It would have reduced a lot of stress and time wasted, to have a visible cooldown timer. I spent a lot of time clearing my cache, restarting my browser, trying different browsers, a lot of back and forth on discord, resetting this and restarting that to the conclusion that there is an unannounced cooldown time.
