seems you missing the point of this plugin ... look for example the medical nade . does not make sense to damage entity's if its goal is to heal .
when you speaking of the owner null part . it sounds like corrupted config bc you did not delete config before an update as was asked in update comments . but never the less . after next full . wipe . delete all nadeplus files and download latest update . so it can generate new files for config . and then see what happens . but no these grenades will not do damages to anything . just the effects each one is made for .... if there is still issues . then lets do it a bit more indepth
