When I try to set block a sign with Brackets the brackets just disappear on the sign. Here is the command: ob> lol
[13:05:03] [Client thread/INFO]: [CHAT] Command set: /setblock ~ ~1 ~ standing_sign 8 replace {Text1:[+train],Text2:"eject",Text3:"0/1/0",Text4:"90/0"}
Confirmed.
Even when adding the missing quotes:
the brackets are not rendered.
