Crash when editing empty field in ESP

[zfih]

Describe the bug
Had an empty field in ESP under blocks. Tried to delete it, which didn't work so I tried editing it and it crashed.

To Reproduce
Steps to reproduce the behavior:
Can't reproduce, but I got it by:

1. Turn on ESP
2. Add custom to block entries
3. Add Ores to block entries
4. Try to delete the custom block entry but nothing happens
5. Edit custom field and crash.

Expected behavior
Ability to delete the field.
This worked fine when trying to reproduce...

It seems like Sodium is responsible to my crash...
