It makes sense there is a sign limit tbh, in large amounts signs can cause massive frame drop. Same thing with item frames and chests, I thank my friend P2 for showing me chest lag on survival lol. I do understand it can be annoying but it's just to keep our gamemode lag less as possible.
More so looking at the bigger picture, with how popular the Skyblock realms are the lag can already be noticable enough... so these restrictions are just to keep everything running smoothly
Thank you letting me know there was a sign limit, you learn new things everyday :)
Also, you can only buy island and hopper extenders from the shop! So 750 signs will have to do the job xD
