hpl.log Errors

[Kleetus]

Hello,

I'm only early in the game, and I'm not having any problems, but I've noticed that I have a huge number of errors in the log.

EG:

There's a lot more than that, that's only about fraction of the errors.

I've tried uninstalling completely and re-installing, and as I've stated, I haven't encountered any issues yet, although I'm not far into the game.

I just want to know if this is any cause for concern or is it normal?

Thanks.
