[1.7.10] Crash from change of wand focus

[demycat]

I had a world where I survive and decided to add automagy, but there was a problem with the change wand focus, minecraft is crash.
I noticed that this happens only in the old world, if you create a new one, everything seems normal.
How fix this?
crash report:
ForgeLiteLoader 1.7.10 (2018-02-14).log

Were you switching from no focus to a focus, from a focus to no focus, or from a focus to another focus? Which focus or foci were involved? It consistently crashes every time you switch the focus?

I don't see anything in the log that makes me sure that Automagy is at fault.

In the new worlds where it doesn't crash, you're using the same set of mods?

If you remove Automagy, does the crashing stop in the problem world? (Back up the world before removing or adding any mod, just in case.)

@Tuhljin no focus did not stand on the stick (I just press the selection button and everything flies)
