Another problem is the core plug-in needed. After packaging the Android terminal, the core plug-in led to ugly lines on the map, which means that I lost the huge player group of mobile phone users. I can't understand English and use Internet machine translation. I don't know whether the meaning of machine translation is accurate or not and whether it can be understood.

Yes, the Farming System requires the Visustella Core Engine and Events to be used, but the rest can be used without them. They shouldn't be causing problems on mobile devices, however, so I would recommend troubleshooting the plugins and mobile devices that you're testing with.
