A malformed client or a plugin like Specter (see issue falkirks/Specter#85) could put incorrect data into the clientData fields, or a MCPE update could even suddenly change this with a new version, causing this plugin to crash.

According to Steadfast2 (not a trustworthy source imo), the "Unknown" "DeviceOS" field is -1
If this is true, it causes this plugin to crash.

Maybe default to "Unknown" if the data received is wrong/not in the arrays?
