Oemof DC-OPF Error

Hello,
I tried to use the DC-OPF model in oemof and recognised a strange behaviour. My model gets sometimes solved and sometimes I get an error back. So I often have to run the code multiple times to get my energysystem solved. After some digging in I realised that the LP file sometimes misses parts. This is my energysystem:

dc_net_test.txt (4.7 KB)

In this picture you can see the difference between the solved and the not solved system.

lopf_not_solved.txt (4.1 KB)

If someone has an idea why this happens I would be very glad and it would help me very much.
