You can give memory to forge 1.7.10 as well. You do the following: in the minecraft launcher go to launch, options turn on advanced settings, find your forge 1.7.10 profile click it, go down to JVM arguments and turn it on, change the first part of coding thing that says -Xmx1G to -Xmx3G this should fix your problem of memory.
Well for all the fans of the map sorry but nothing really big has happened. I will however be thinking of the next update and what i will add. Also please give me your feed back and tell me what you would like to see in this map.
