Viewing post in v1.1.0 - Detailed Waypoints & Templates comments
Sorry for the delay we’ve been very busy. So we took a look at the plugin and are unable to reproduce the problem. We created a new game project with RPG Maker MZ 1.6.1 and transferred the demo files over, all files successfully copied including the common events which will ensure the Waypoints are added. We hit play-test and look at the Waypoints menu and they were available for us and all items were displaying correctly.
You can send us a demo at our support email and we can take a further look for you. support@ltngames.xyz
