Respawn's bed bugged [Resolved]

I might have just found a new bug... I was at the nether when i died, then i didn't appeared in my habitual bed, i appeared in the first spawn...
It said that my bed was obstructed but it isn't true, my bed was in a secure place in my 'advanced' home that i made for 2 weeks.

Im not sure but... i think it is a bug.

Greetings.

PS: Now, i'm lost ;( xd
