No, it's my game. I'm stuck on the main menu for ten seconds. If I'm quick, I can click "Start Game" and then it freezes on that screen instead, nice change of scenery.
Out of curiosity, I moved support_updater out of my add-ons folder. The pause disappeared. Of course, Glass thought I had lost my mind, and I couldn't decline to redownload the updater, so I moved Glass too, and all of a sudden I can get in-game ten seconds quicker than usual.
I downloaded Glass from the website, no pause... I let it download the updater, restarted the game, the menu appears, and everything freezes. Ten seconds later, control is returned.
So, yes, it's absolutely related to the updater. I'm not stupid, Greek.
If it still has any effect on how you think of me, I'm sorry for once reacting very harshly to a Christmas greeting appearing while starting Blockland. It freaked me out. I didn't expect to see an enormous .jpeg unless I put it there. Reminded me of dreams about computer viruses.
Ok, I'm a little stupid. I made a new Blockland folder, put the basics in, and was putting add-ons back in, restarting with no pauses, developing the intention of saying "well I guess it works now *shrug*" but after restoring the last batch of add-ons, the pause has returned. I'll try to figure out what's doing this.
