What version of Necrosis LdC are you using?
3.0 (r221)

What is the problem? Please describe what is happening and how to reproduce it.
Necrosis has the option to show buff timers. The problem is that when I have Decimate proc for the first time, the addon shows I got a 10 minutes buff of Decimate. It doesn't reset when I get the proc again nor when I kill the target.
This effectively means I can never know if I have the buff or not.

What is the expected output? What do you see instead?
Proc like all the other procs, at least until you make a standard procedure to handle execution effects (Decimates @30% and Drain Soul @25%).

Do you have an error log of what happened?
Nope, the addon does not consider my problem as an error.

Does the problem go away if you disable all addons except for Necrosis LdC?
Nopes.
