Hey guys, A user on my server can't die, so i though: oh we is using hacks. But he said so: so i went on his computer though TeamViewer. Deleted his .minecraft, and he was still unable to die. 1. We are using bPermissions, every user is default user. We are not using any kind of AntiBuild plugins like Modifyworld, or AntiBuild. 2. He isn't using /god. 3. He isn't dying from anything. You hear his charater crying if he is in the lava like: ''UH UH UH'' but he is still not dying. The weird thing is, his sister has it too! So i THINK it's not server-side. Thanks guys!
Try running without plugins. Try deleting his user data in essentials or whatever else you use. Delete his userdata in your world files. If this doesnt work then idk. lol
If him and his sis both have the problem on the server, then it may be their ip's issue. It may be possible that their internet is very laggy, causing them to some how teleport around, and in a way escaping all harm. That has happened to me before on a different game. Idk it's just a guess. Try their same accounts and same .minecraft except using a diffrent internet. Hope I could help.
