Possible issues with 1.16.x?

[Magicrafter13]

Just added this to a fresh 1.16.1 spigot server (papermc), and it appears the plugin isn't ready for 1.16 yet, unless there's something odd with my setup.

try build 32 from https://ci.codemc.io/job/Fungus-Software/job/Bssentials/lastSuccessfulBuild/artifact/Bssentials/target/Bssentials3.jar

[Magicrafter13]

@IsaiahPatton no difference

[pisaiah]

what about build 33? https://ci.codemc.io/job/Fungus-Software/job/Bssentials/lastBuild/artifact/Bssentials/target/Bssentials3.jar

[20:02:27 WARN]: Legacy plugin Bssentials v3.0-b33 does not specify an api-version.
[20:02:27 WARN]: Legacy plugin bPermissions v2.12.3 does not specify an api-version.

The warning still exists, but the error is gone now. Is build 33 the newest or are the newer versions? I download the plugin from https://dev.bukkit.org/projects/bssentials I'm not familiar with the site you've been linking to.

(Also should I close the issue now, since I assume the warning isn't that important?)

Wait, now I get an error every time a user joins! (Or at least every time I join...)
