The map that I'm loading is a map I made in 14w20a.
Steps:
Make a map with a sign in 14w20a
Load the map in 15w35b
Only the first word of each line is displayed
I'm not sure how this is a duplicate, one is about empty lines becoming "null" and this is about only the first word of a line actually being visible.
It's also still not fixed, whereas that bug is closed and fixed.
EDIT: By loading my world in each snapshot upgrading 1 at a time, the issue is no longer there. However, empty lines are replaced with null starting with 15w32c.
Having the same issue:
1.8.8:
15w34b:
[media]Still in 14w27a.
Confirmed for 14w26c.
This is a problem with resourcepacks, for some reason redstone dust has been rotated 90 degrees. Try downloading the snapshot version of Faithful.
It used to, but 14w20a -> 1.8.8 -> 15w35b works now.
Thanks.
