Persistent Technical Issue

Good day!

Recently, I’ve been facing one weird issue during any RP.

For some reason during any moment of the RP, I receive an error message. I press “resubmit” and all goes smoothly as usual. But if I restart the page at any moment, even after the error has passed- pace of dialogue changes completely. I may start receiving messages that bot sent 3-7 messages ago and so on. Like it shuffles its own messages or forgets/deletes its own or mine responses. Any idea what might be the issue or how can it be fixed?

P.s. I hope I have explained everything correctly, just in case.

Thank you for your help!
