Window Size Problems

Not really sure how to describe the error, but when I load the game the window is incorrectly scaled and I have to go to settings --> video --> resolution --> go windowed; then go fullscreen again to fix the scaling. It isn't really that big of a deal, but very annoying to have to go through every time I want to play. the first image shows what happens if I try to just hit the fullscreen button (I'm on mac), but if I set it to fullscreen through the method above, it does the second image and I h...

wierd world-specific crash upon joining world twice

Game sometimes crashes after trying to join singleplayer world.

So I'm trying to put a pack together with Calamity and Remnants being the main content mods and sometimes as soon as I finish loading my singleplayer world I created before downloading the mods, it crashes. I'm not sure if it's because its an old world or what but I'm able to load in and play on the world just fine sometimes when it lets me in. It's just a really odd and inconsistent issue that'll crash like 3 times in a row sometimes and then just work on the next launch. Here are my log files:...
