Description
(About the Well-Known Bug of the Sculk Horde mod by GRMikeatron)
The following ID's have no texture associated or translate on en_us.json file:
"sculkhorde:perimeter_ward_relay_block";
"sculkhorde:perimeter_ward_emitter_block";
So I fixed it by adding 2 simple textures to each block and translating it on English, also adding the json files.
(Soon changing the textures)
