Mate judging by your log something is crashing when you hit the hotkey for dump placeables. I just checked and the Insert Key is the one that issues that command. You could easily check by pressing INS ingame to see if you can force a crash. That said I've done it and it hasnt crashed my client.
If it crashes then you can a) not press INS or b) reinstall the program ensuring that all plugins, routines etc... are upto date etc...
I suspect that the problem with the dump placeables command is actually to do with whatever items it actually dumps not the command as such.
I'm guessing that you've bumped the key and gotten the crash and that If you continue using the bot without pressing insert then you probably wont experience the issue again.
- just a noob here so im only speculating on the issue
