Yep, I call observeRoom() every tick, (I have a stored 'Unreachable Room' in memory and in the end of each tick I'm using that value)

 when I observe nearby rooms it doesn't always return them on the next tick, 
in fact it returns it one time and doesn't on the next

not sure what's the reason for that

I'm getting this error nad everything is dead, nothing being digested on tick:

'Script execution has been terminated due to a fatal error: Cannot save more than 10 memory segments on the same tick'

I've tried to play with the RawMemory on console, not realizing I've removed the link to spawns/creeps/rooms...

how can I return the memory to work like it originally did and return links to their original state?
