MC Server Type & Version: spigot 1.9 MythicMobs Version / Build: 2.3.2 #1441 Do you see any additional errors on MythicMobs load/reload? no Please describe in detail the problem you are encountering and the steps to replicate it Vanilla targeters (with any combination of arguments ive tried so far) are reluctant to work if the "radius" argument isnt provided. Simply using @a or @p won't work. Neither will @a[c=1] or @p[c=3] for example. It must have @a[r=100] or @p[r=30] . Some radius must be given.
