I can confirm this report. i have multiple TP-Link WR1043ND v3.0 which exhibit the same behavior. 
Usually, both the WDS station and the WDS AP report in CLI/LUCI a connection, but no data is transmitted over the wireless link. sometimes the RX speed is locked to 1 MBit/s or the AP disappears completely until reboot. reboot fixes the problem until it's happening again at random intervals. log files are clean.
