I am getting this too (ver. 6.314 com). I think it is because I have 43
includes. This restriction makes it difficult to create, debug or modify a
modern game because of the large amount of code needed has to be
consolidated into no more than 40 files, forcing you to mix code for
dissimilar things into each file. This makes it much harder to find the code
you are looking for to debug or modify.
Is there any way of upping this? Could it be increased in the next update?
