This has suddenly happened to me as well, after several successful uses of this ability. The difference between this instance, where it doesn't work, and the previous instances, where it did? I'm using tokens not-made by Devin Night! However, that's not entirely accurate; I have a still-functional set using not-his tokens. Maybe the difference is I'm using ones from dundjinni? Nope; the working one uses some of those as well. Here's the situation: I have a set of goblins; it works fine. I have a set of orcs; it works fine. I have a set of zombies; it works fine. I have a set of frogs; it doesn't work. The frogs are the most recent set made, hence my posting an error regarding them. For the frogs, I have five different images. The three made by Devin Night work. The two from dundjinni do not. I can change any DN frog to another, randomly. No frog from DN will change to a dundjinni frog. No frog set up initially as a dundjinni frog will change to a non-dundjinni frog. I removed one dundjinni frog from my rollable table and re-set the default token to the remaining dundjinni frog. I placed 9 instances of this frog on the grid; none change images when randomized. I placed 9 instances of the original DN frog on the grid; Some change images when randomized, but only to DN frogs. The chat window continues to show a full variety of images, despite those on screen changing 'sporadically' is I guess the best word for it. Interesting note: Despite removing one of two dundjinni images from the rollable table, the original set continues to indicate that it could, if it were working properly, include both dundjinni images in the random change; this is also the case if I choose sides. Here's an image that may help explain: Original Set: red, green, grey frogs, all Devin Night; Blue and Yellow, dundjinni; note lack of blue and yellow frogs; note presence of blue frog in 'change side' window. Copy Set: as above, but without blue frogs. Zombies: variety from many sources Orcs: All Devin Night From this, I am unable to logically determine any contributing factor that is not ruled out by working in another set. Experiment done: Copy campaign. Result: Interesting, to say the least... Absolutely nothing was done to this copy aside from entering it. Note that some of "Original Set" have changed; specifically note the blue and yellow frogs. Note that many of "Copy Set" have changed; specifically note the non-yellow frogs. Now I will go through and randomize each set, once. The results: Original set: lower-right frog changed from green to red; within bounds of chance except for DN/dundjinni issue. Copy set: upper-left frog changed from green to red; within bounds of chance except for DN/dundjinni issue. Zombies; Changed as expected, randomly. Orcs: Changed as expected, randomly. Windows 7, Flash 11.9.900, Chrome 31.0.1650.63 for what that's worth. Not sure where/how to find these 'errors' mentioned in a previous post. I'm way, way, waaaaay past my bedtime now, so I won't see any response until tonight. Thanks for looking into this; hope my data helps! PS: I've sent Kristin a private message containing a link to the copy of this campaign for closer examination. If GM access can not be obtained by someone on Roll20 staff, I will provide it when I wake up. PPS: I'll send one to Riley and one to Gauss as well, 'cuz y'all rock pretty hard too!
