since godot beta5 my project is broken.
dozens of errors on parsing problems
could not parse global class etc.. (on startup)
for example
E 0:00:00:0547 is_type_compatible: Parser bug (please report): Trying to check compatibility of unset target type
<C++ Fout> Condition "!p_target.is_set()" is true. Returning: true
<C++ Bron> modules/gdscript/gdscript_analyzer.cpp:4097 @ is_type_compatible()

DaveTheCoder ive looked at the issues on github and found it has been a problem for some time now. but i never had the issue before.

what exactly is a parse error?

A parser is the part of a compiler or interpreter that scans the program text (or any intermediate code or symbols) and breaks it down into tokens and symbols for translation, usually building a data structure.

It makes "parts" (lat. pars), that's why it is called parser (I think) :-)

That message seems to imply that the program has detected some inconsistencies in the parser, that tries to make an operation on an "unset target type".

It asks to report this as a bug.
