Resource file named with .html suffix

After updating to 3.2, extant project would not launch in debugger (iOS or Android); second, extant project would. Subsequent updates failed to resolve. Renaming file "Resources/documents/<name>.html" to drop ".html" suffix (or change to e.g. ".txt") resolved problem. Biting of tongue and other unmentionable angst. Project had been working from 1.8 until 3.2 (or perhaps 3.1). FYI
