This is not a deobfuscation problem. The read pcode list is invalid. So the problem is in AVM2Code constructor. For example: ; 5d 9d 14 ofs00096:findpropstrict Qname(PackageNamespace(""),"addChild") ; 14 d2 4f 9d ofs00098:ifne ofs-6467528 ; d2 ofs00099:getlocal_2 ; 4f 9d 14 01 ofs00100:callpropvoid Qname(PackageNamespace(""),"addChild") 1 ; 47 ofs00104:returnvoid findpropstrict instruction is 3 bytes, so the next instruction shuold be the getlocal. But between them there is an if. (probably it is from a lookupswitch) Jump offset is negative, but it is not a problem, deobfuscation fixes it. The problem is that the next instuction after the ifne was not read. (At offset 98+4 = 102) Maybe I'll check this later, but currently I'm working on finding other decompilation errors, so you can check it if you have time.
