Teamfight Tactics Season 5 is currently one of the most talked-about seasons among gamers as the power is no longer concentrated in the expensive units but is more evenly distributed, with the introduction of dark items and unique metas… However, there are also numerous factors within that make players uncomfortable.
Recently, another bug in TFT Season 5 has been discovered by players. Specifically, when players have low health (below 10), a bug sometimes occurs that causes their health to drop below zero, resulting in an immediate loss even if they won that round and did not purchase Teemo or have any other influences, even when their units still have plenty of health on the board. Notably, this bug often occurs just before entering the shared selection round.
This is an extremely serious bug and will ruin the strategy of accumulating gold through a “losing streak” because players cannot predict when the bug will occur. Moreover, sometimes players may have around 1 or 2 health but can still pull off spectacular comebacks, and none of this would be possible if the bug appears.
On several TFT forums, many players have complained about this bug, and numerous high-ranked players have confirmed that they have encountered this type of bug at least once in Season 5, and it still remains unfixed to this day.

It can be seen that while creating an incredibly engaging TFT season, Riot still appears to be quite slow in fixing bugs, especially those that can severely impact player experience and their rank.
