I don't know if this is expressly exclusive to rabbit leap and long jump, but as of this new update, it seems that on relog and potentially even battle end, rabbit leap and long jump simply... unequip themselves! You have to equip them again, and this can easily catch you out if you're not looking, and don't realise. I had another rabbit (Hibari says hi) also confirm that their rabbit leap and long jump had unequipped too in these circumstances.
