I tried LSPD just to confirm LSPDFR works as intended. Here's log with going on duty as BCSO directly:
After going on duty as BCSO, the issue reoccurred, and when I used forceduty command, it returned my character as off-duty. Following forceduty command caused crash. (Foreign language in Exception message read something like: "Thread is either in operation or has been terminated. Cannot restart. ")
I skimmed through the log, and there seems to be some issue with Computer+ plugin. So I removed it and tried again.
Unfortunately the issue still occurred when going on duty as BCSO, but this time, forceduty command crashed entire LSPDFR, so I reloaded LSDPFR plugin.
After successfully loading LSPDFR, and issued another forceduty command, I was able to go on duty as BCSO with everything functioning.
I tired again just in case, and same thing happened. Issue occurs, forceduty crashes LSPDFR, and I was only able to go on duty as BCSO after reloading crashed LSPDFR and then using forceduty command.
