Hi, i had complete the same problem, every time i reopened a random generated map, or i played the map. I got the messages like this, sometimes more or less: 2345.345 javascrip warning: Script value conversion check failed: v.isnumber() (got type object) After a little analyse of the .xml file i detect some odd like this, because i cant reproduce it on e NEW map WITHOUT random generator. <Entity uid="4895"> <Template>mirage|gaia/flora_tree_pine</Template> <Player>0</Player> <Position x="753.06516" z="1555.99155"/> <Orientation y="-4.31946"/> <Actor seed="2935"/> </Entity> Inserted in a NEW MAP .xml file you get the same errors, and see no tree. So you have to delete this "mirage|", then you see the tree and the error is gone. d()b and should look like this: <Entity uid="4895"> <Template>gaia/flora_tree_pine</Template> <Player>0</Player> <Position x="753.06516" z="1555.99155"/> <Orientation y="-4.31946"/> <Actor seed="2935"/> </Entity> You have to reload the ATLAS, reopen do not work! There are different amounts of errors every new random map (1-xxx), so it is the best you get an good old editor or an similar one, to delete the "mirage|" all at once.
