CAUSE @ EFFECT
Whenever you place sugar cane adjacent to cactus the cactus will just stay there differing from its normal behavior.
NOTES
I am not 100% sure this is a bug it may be just a cool feature.
Sometimes it happens out in the wild.

Sometimes a cactus can spawn touching a desert temple but not break.
