You can write your review of the 0.5.1 release here. If you get crashes, please copy the output from the launcher and make a new thread in #bug-reports.
- Saving, of course.
- No crashes nor lags.
- Sometimes after I exit the editor the cell spawns two cells instead of one.
- Iron chunks still spawn onscreen.
- I still have the same compounds of the last session after I exit the editor.
