Arena Tournament Bug

[Jiminimonka]

I ran a tournament today, with an entry cost of 100.

However, only 2 of the 5 entrants paid 100, the others paid 30 or 50 as you can see in the copy of chat below. The winner was the viewer that paid 30 of the initial 70 entry fee.

[09:24:23] <jiminibot> : Emperor jiminimonka is announcing a grand Tournament Arena. The weak shall fall and only the strongest shall walk away with riches and glory. Entry cost is set at 100. Are you strong enough? Type !joinarena to enter.
[09:24:34] <jiminimonka> : !joinarena 100
[09:24:38] <stormquoll> : !jimibeans
[09:24:38] <jiminibot> : JimiBeans : stormquoll [Red Cabbage - Braised] - 136
[09:24:50] <jiminibot> : Welcome to the channel racthoh
[09:24:54] <iceborger> : !joinarena 100

[09:27:23] <jiminibot> : 5 fighters have entered the grand tournament. The weak shall wither, the strong shall prevail, only the best will walk away with riches and glory. Let the battles begin!
[09:27:48] <jiminibot> : What a jaw dropping show of valor! In 3rd place with 1 victories and 75 JimiBeans in winnings is stormquoll. Coming in 2nd place with 1 victories taking away 125 JimiBeans is jiminimonka.
[09:27:49] <jiminibot> : And.....the glorious Champion of the Arena, with 3 straight wins, taking out the top prize of 300 JimiBeans is nbarnett.

I believe the bot automatically takes the minimum required entry fee if you type under that figure, if you have the currency for it.

Jordan is correct. For tournaments, the entry cost is fixed, so the second number is not needed and is ignored.
As long as you have the minimum amount (entry cost), your entry will be accepted.

This is working as intended and is not a bug.
