What can shoot past the barrier

On old mobile this can produce a forcefield, automatically pushing any wild animal inside the radius of the forcefield outside. The forcefield also has an animation where it pulses out from the center of the tek generator then stops, showing where the forcefield ends, then the animation loops.

That's all since I'm too scared to play on pvp to give extra details about the forcefield and even if I did I probably would never be able to get close enough to a forcefield in someones base before I died plus there's always hackers in pvp servers.

Also if you didn't know tek stuff on old mobile can be powered by regular generators instead of tek generators so instead of fixing this bug they just added a forcefield to the tek generator to give it a use.

Arthropurea can damage the Tek generator

How can it be destroyed like what can damage it? Please I need help
