I and a few players have noticed that TNT is not behaving as we expected, I've tried loading EHM on a private server with no other plugins and increasing the explosion power for above and below border up to 50, yet TNT does not seem to increase its explosion size at all.

MC Server version: git-paper-221

EHM Version: 3.14.0-e490375

I've tried enabling DEBUG but nothing came through in the console related to TNT or even block changes. Please advise.

I'm seeing the same thing. Disabled other plugins and changed the tnt explosion power but it does not increase the explosion damage at all. Seems to just be vanilla behavior.

I'm using the latest spigot 1.14.4
ehm: 3.14.0-e490375

Hmm, wonder if this has been changed/deprecated in the spigot API.

It's using world#createExplosion(double x, double y, double z, float power, boolean setFire, boolean breakBlocks) so perhaps spigot is no longer using that value. Maybe it has a cap. Idk.

The multiple explosions should provide extra power. I'll see if I can write something to test plugin-generated explosions.

i noticed it doesnt generate multiple explosions as well.
Not above nor below the border. TNT seems to be rewind to vanilla completely, except the "shoot blocks away like debris" thing.

Multiple explosions aren't created? Please test with older versions. It's not easy to see the multiple explosions as they all happen simultaneously.

Here visual of testing in EHM 3.14.2, spigot 1.14.4 with tnt and charged creepers:

Sorry if i keep spamming here.
I found this plugin which lets you configure TNT.
If you set tnt radius to 50 or 70 it works like EHM tnt used to.
Maybe RoboMWM can have a look to figure out the explosion functions as well.

Need comparisons to older versions

Can confirm that TNT behavior is back to vanilla. Brand new server, no other plugins.

Need comparisons to older versions

What sort of comparison are you looking for? It's been years since I last ran a Minecraft server.

"TNT behavior is back to vanilla" means "TNT behavior is not EHM's TNT behavior" which means, yes, no multiple explosions, no customizable size, just the standard no-plugin behavior.

I'm not really winning to take the time to compile a bunch of older Spigot versions to see what version EHM's TNT broke on. I'm between desktops at the moment and compiling Spigot for 1.14.4 took an hour. Sorry.

Trying to identify when this occurred. As far as I'm aware, nothing has changed in the code which I reviewed a couple months ago, so either it's working in an older server version (which is what I believe is the case - some change in the server code), or in an older EHM version (meaning there was some change in this project I was unaware of).

i noticed it doesnt generate multiple explosions as well.

Is also puzzling to me - was this the case for you as well?

compiling Spigot for 1.14.4 took an hour.

Try using Paper? https://papermc.io/legacy

I checked that ultimatetnt plugin, and it's manually performing logic to remove blocks within a specified radius.

I made a test plugin and can confirm that world#createExplosion works on 1.16.1.

I then tested with EHM and changed the relevant config options (...TnT.Below Border.Explosion Power and the Above Border node as well) and observed similar behavior to my test plugin.

Since no configurations have been provided here I'm going to assume either you guys made an error in the configuration (I did initially, I changed explosion power for creeper instead of TNT - though explosion power for creepers did also work as intended) or there was something wrong with spigot's API in the prior version for that method.
