I seem to be having an issue with the application where the tabs for World and Biome Settings are not showing up. I assume they're supposed to based on the cursory glance at your code, and that it's not because they haven't been implemented yet in 1.0.13. I can't get them to appear no matter the scale, and even reopening it doesn't help.

I'm on Windows 7, fairly old hardware, wouldn't be surprised if it's just me... screenshot attached.

On an unrelated note, is OTG and OTGEdit safe/useful to use for 1.12.2? I haven't run into anything disastrous, but wonder if something might be missing, as OTGEdit OTG/TC version only goes to 1.11, though Curse shows it's for 1.12...

*Sorry for the late reply!

Hey, yeah you can use it for 1.12.2, although I'm not 100% sure if there are no new settings introduced in OTG for 1.12.2, if there are those won't show up in the UI yet (still have to double check and if necessary update the versionconfig.xml that contains the settings).

For the tabs problem, looks like the current tab has been dragged out of proportion/position in the designer view, the top of the current tab is over the tab controls, so you can't switch tabs. Did you build from visual studio or are you using https://github.com/PG85/OTGEdit/blob/master/Build/OTGEdit1.0.13.zip?

The zip file (I'm 99% certain, but my desktop is borked so I can't confirm, but I know I didn't build anything). I thought I mentioned this already, but I tried loading it up on my laptop running Win10 and the tabs seem to display properly. Thanks for getting back to me.
