Rescuing print just counts it as completed

Hello, I just recently started using Repetier Server/Host with my Anycubic Kobra Max, which is on its latest firmware, reportedly some version of Marlin. I have the rescue mode enabled, but whenever I reconnect, it initially replays the already sent codes as it's supposed to and then continues to act as if the print completed successfully. I have it connected via USB B cable that came with the printer, and most of the time prints go fine now, but when there's a disconnect and I try to recover the print, it does as mentioned above. I selected a comm setup with ping pong mode enabled and that drastically reduced the connection errors I was having, but after doing such, I had a disconnect and the same issue with the rescue attempt happened. Logs for the print before and after the disconnect and rescue below, shortened to relevant parts. Any help is appreciated. 

The disconnect.

  • Testing shows that something with recover is broken, most likely in 1.4.x switch. Will fix it for 1.4.3.
