Manage role didn't work and also not throw any error about jda

[MinnDevelopment]

The HierarchyException is thrown by addRoleToMember, before you even call queue. Are you sure that you properly handle exceptions being thrown?

When I call the method guild.addRoleToMember it didn't throw any exception.
And the bot did have the permission to manage the role but the roles higher than the bot's role will not work.

And no matter the bot's role is higher or lower than the target the method won't throw the exception.

I just tried this again, and it definitely throws an exception:

net.dv8tion.jda.api.exceptions.HierarchyException: Can't modify a role with higher or equal highest role than yourself! Role: Role:highest role(id=280161492307804160)
	at net.dv8tion.jda.internal.entities.GuildImpl.checkPosition(GuildImpl.java:2031)
	at net.dv8tion.jda.internal.entities.GuildImpl.addRoleToMember(GuildImpl.java:1688)

Since you also called your variable linkedRole, it might refer to a managed role, in which case the request fails with a failure callback:

[pool-1-thread-11] ERROR RestAction - RestAction queue returned failure: [ErrorResponseException] 50013: Missing Permissions
net.dv8tion.jda.api.exceptions.ContextException
	at net.dv8tion.jda.api.exceptions.ContextException.here(ContextException.java:54)
	at net.dv8tion.jda.api.requests.Request.<init>(Request.java:77)
	at net.dv8tion.jda.internal.requests.RestActionImpl.queue(RestActionImpl.java:203)
	at net.dv8tion.jda.api.requests.RestAction.queue(RestAction.java:573)
	at net.dv8tion.jda.api.requests.RestAction.queue(RestAction.java:539)

The same happens if for some reason the position check in JDA fails.

Please give me an easy to reproduce test-scenario, if you still encounter issues. Otherwise, I have to assume this issue is an incorrect handling of exceptions on your end.
