Brand Ult Bug

Ok so. There was a patch where they fixed a brand bug where it was said that the ult kept bouncing till it killed someone. It was said that it was fixed. Although I played brand all the time, I never noticed that bug. The max bounce was always 3 on any target. And that too, you needed the target to be ablaze for that and things to bounce with. That was a weird fix, but ever since then, I encounter this same bug lots of times, Where my R doesnt do any damage at all. It goes in, disappears after one bounce even if the target is ablaze and there are minions around, but that one bounce, it doesnt even do any damage to the enemy. It just keeps happening a lot and pisses me off and tilts me hard. Even my enemy teammate i was against at mid noticed it and told me to report it here and that it was a really big bug. Please check and fix. I have no recording, but my last few games have had that happen way too many times.
