I have an issue with the one-at-a-time mode of printing multiple objects. Whenever I print two object (or more), after completing the first print, my hot end will somehow hit the first print and drag it with it to the area for the next print. The last time this happened, I lost both of my prints (duh) and had to completely re-level and adjust everything because the hot end literally smashed into the part it dragged. Is there any way I can make it stop this without going to all-at-once mode? Any help is appreciated. Thanks.

Go to "file" "preferences" and make sure all the values in "printer head size" are the correct dimensions for your printer. Hover over each value to see the recommended settings. You might want to instead run the wizard first (first 2 steps only) to setup these values to defaults.
Now Cura should:
1) Put the parts far enough apart
2) print them in order away from the fan first so that the fan is never near a finished print
If you really want to print all at once just set gantry height to 0 or set it to a value smaller than your tallest print and Cura will switch to "all at once" mode.
The problems with all at once mode:
1) Speed - It is much slower due to retraction and moving over to the next part. Possibly twice as long - why not just print them one at a time and remove after each? I know if they are small, quick prints it's better to print all at once.
2) Stringing - you might get some stringing between all the parts if you can't tune it just right.
3) surface quality - leaving and coming back to the external skin causes the part to not look as good
4) Disasters - if the print fails you lose all your prints instead of the current one.
one-at-a-time mode has one bad thing about it -
when is about to start the next print sometimes it extrudes/leaks onto the just finished print.
