teleport mob spawners in 1 in 1 second to the same spawn localization
stop mobs movement, stop animals movement.
i test in spigot 1.12.2+ and working.
this plugin also reduces the cpu consumption of the movement of entities.
100 entieties x 20 ticks = 2000 ticks for second.
my plugin: 1 tick for second x 100 entities = 100 ticks for second.
100ticks/2000ticks = 0.05%
you can enable profile-profiling: false to true in bukkit.yml and test / timings on and / timings paste or / timings report
