[BUG] typing [private] on protected signs in rg breaks them

[Kiomaku]

so basically when the players right click on a sign even that sign is in a protected wordguard region
by typing the
[private]
could break the sign and it errors the unknown format typing on the signs

this works for
BAMBOO SIGNS
all hanging signs
and there may be other signs too im not sure,
