I am unable to access my map.😭😭😭

Currently, I can only access my old map; attempting to access the new map causes the game to crash.

Ptag memory

If you encounter java.lang.OutOfMemoryError: Java heap space error, that means that the game ran out of memory (ram) while processing your request or action.

If you're on mobile, there's not much you can do to alleviate this issue, closing other applications in the background might help. For PC, you can simply increase the maximum heap space as a launch argument. For example -Xmx4G will let the game use up to 4 gigabytes of memory. That is, of course if you have enough memory. Generally, it's not a good idea to allocate more than 50% of your entire system memory. If that doesn't work and you're on PC, please check if you have 64 bit Java installed, because if you don't, game can only use 2 gigabytes of memory.

However, this is a newly created map that isn’t particularly large. On my other map, which I’ve been playing with for a long time, the population has reached 1.3 million without this issue occurring. Could it be because I renamed all the stations? I renamed all the subway stations in Chinese.
