Assertion failed updating wireless network

[thedeadferryman]

I've set up a config with a bunch of drones and a PC that communicate over the wireless network. However, this error randomly raises sometimes:

Here is the crash report file: crash-2023-03-11_21.04.36-server.txt Log and debug log files: 2023-03-11-2.log.gz debug-1.log.gz.

Minecraft version is 1.12.2, OC version is 1.7.5.192. Config is slightly modified (to allow a bit more EEPROM space and make assembler/disassembler faster). Here it is: settings.zip

UPD: This problem keeps raising randomly even in the newest version of OC (1.7.7+5413028).
