This actually seems to be something intended by the original programmers rather than a programming error. Are you sure this is actually not necessary?
For example, if you call ->Is_Valid() with a nullptr object this function will return false rather than crashing the code.

This should take the sizeof(field->ID) rather than hardcoding it to 4. If we decide later to change this in the future this memcpy would be very error prone.

This is replacing a very optimized copy of palettes with a potentially non-optimized one. Are you sure this is necessary?

use ARRAY_SIZE, defined in common/macros.h

size_t may be cleaner than int here

Avoid calling strlen in a loop comparison like this. This is O(n²) instead of O(n). Instead store the size of the string into a variable and use that instead.
