Cause:
The size that is given in the file for the length of the chunk includes the compression byte, thus when reading a chunk that is at the end of the file, it would read 1 byte more that should be possible, causing a panic.
- Load chunk (0,0) only in debug mode. This prevents crashes when the chunk for (0,0) does not exist, since this is only used for checking the size of the chunk packet.
- Remove log: `Getting chunks x, from region file y`
