Low Pet disappears when farming

Description of the bug:
After the event begins, it came to my attention that my pet (a black bunny, if that matters) would disappear from time to time as I (a lv 104 hermit, if that matters) walk around, climbing rope up and down platforms when farming. The latest patch does not solve this problem. You can double click on on the pet in the inventory twice to re-activate it.

Auto-potion still works, but obviously no meso/item pick-ups. I also noticed that my pet falls from sky more often than it used to be. My hypothesis is that it gets stuck somewhere out of the screen when repositioning/respawning when it becomes too far away from the character.

What is supposed to happen?:
Pets should not disappear as long as they are well-fed

Where did you find and/or notice this bug?:
Maps where you need to climb up and down platforms. It seems not to be a problem when you do not have to climb ropes or get on and off different platform levels.

A step-by-step guide to re-producing this bug (optional):
Find a map where there are platforms, hunt with your pet normally as you climb up and down platforms, then it would disappear after some time.

Extra information (optional):
Found this problem in some deep ludi maps, showa street, among others
