For my future reference, in case I wonder why I use biglyBT on Linux but qbittorrent enhance on Windows:
The BiglyBT somehow keeps crashing when communicating with other clients, might be a problem with i2p, but I can't reproduce the issue and the log shows nothing. So I switched from biglybt to qbittorrent on Windows, while kept using biglybt on Linux to download things from i2p.
