About saving - playing on a weak machine. Saving with Space Exploration and our map takes about 12 seconds, but if there is at least 1 record in the log, it takes about 30 seconds. At the same time the second time will not be so long (if you leave the same log). But this I have not yet convinced to the end.
About the error - I saw it by accident. But in the game itself, I did not see anything. I just clicked on the only line of the log to remove it, well, it was immediately deleted. Although in that case it was more like a log of 5 lines, each of which I successfully removed. But you can see the logs themselves in the message header.
