[McMemer]

Whenever I load a schematic and press done my screen freezes then after 2 seconds my screen goes to the loading a world screen and takes me back to my launcher where I am shown the crash report

[Lunatrius]

You are running the game with 512 MB of RAM. Try increasing the amount of RAM for the game (1GB or 2 GB are more than sufficient) or lower the rendering distance.

[McMemer]

How do i do that...?

[Lunatrius]

It depends on the launcher that you're using. This video shows how to do it in the new launcher: https://youtu.be/zkoFuP8kKEs

[McMemer]

I use the old one just because i think its easier

[Lunatrius]

Which old one?

[McMemer]

One right before the new one

[Lunatrius]

In that case it should be in the Options menu if I remember the correct one.
