Stop process

[Vlasov-Serg-78]

For the last day there were several falls, all of which led to the stopping of the process.
In all cases, the console had a message:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0xb5a5b3]
