No offends, but probably it’s more easier to fix it, they need to reproduce the amount of time the bug, change the code interaction, try to replicate the bug, and then if this doesn’t work, recreate the champion again, or rewrite differently the code, maybe they are trying on the hardway, or they cannot replicate the bug as many times they want, so in this case the best solution is to rework/recreate the champion, as far as I know the bug occurs when nunu cast his e when he enters on the bushes, there’s to many ways to think and try to fix this (probably riot thinked about it) so the optimal solution would be try to change his e, or create the same champion but executed with a different code.
