Yes, noticed that right after I already posted the comment.

I have a similar issue, but I experimented around with it. Repeaters only look as if they were on full delay, but still have smallest one. In fact all of them are "reversed":

• Repeaters which are supposed to be 1 tick delay display as 4 ticks delay

• 2 tick repeaters display as 3 tick ones

• 3 tick ones display as 2 tick ones

• 4 tick delay ones show up as 1 tick delay

The glitch is only optical, though. They still act according to the number of times they have been right-clicked.

Forgot to add: I am in 14w27b too

Hello. The same has happened to me with two worlds.. 😞
My device is a Galaxy Mega GT-I9205 running with Android 4.2.2

i love minecraft (:

Well, for me the problem was an outdated Java version. Perhaps that also applies to you too?
Also, when I said "the issue never occured on Windows systems", I meant windows systems I played at, not that it never ever happened in history.

Seems like that was the problem. Upgraded from Java 6 to Java 7, now it works fine.
Hooked a command block with /summon Fireball to a rapid firing clock and nothing happened so far.

Attached the logs. Names are pretty much self-explanatory. forced is the one caused by F3 and C, fireball is the one caused by the summon.
