Should be in pretty good shape, although there is a known bug with error messages stemming from broken eyelid raws with forgotten beasts and other generated creatures. Doesn't seem to hurt anything too much, but I'm looking into it.
Sounds like an issue with one of the raw changes that was in vanilla 0.34.05.
From file_changes.txt:
body parts
new eyelids in rcp body
body plans
fixed r_eye/l_eye
I think [BODY_DETAIL_PLAN:STANDARD_HEAD_POSITIONS] is what was changed. This is what it looks like in .34.05:
[BODY_DETAIL_PLAN:STANDARD_HEAD_POSITIONS]
This command lets you assign a position within the parent to all bodyparts that fit in a group.
[BP_POSITION:BY_CATEGORY:NOSE:FRONT]
[BP_POSITION:BY_CATEGORY:LIP:FRONT]
[BP_POSITION:BY_CATEGORY:TONGUE:FRONT]
[BP_POSITION:BY_CATEGORY:MOUTH:FRONT]
[BP_POSITION:BY_CATEGORY:CHEEK:FRONT]
[BP_POSITION:BY_TOKEN:R_EAR:RIGHT]
[BP_POSITION:BY_TOKEN:L_EAR:LEFT]
This command lets you establish a relationship between bodyparts within their parent bodypart. The number establishes the extent to which the relationship holds (only used for bodyparts, not the tissue relationships above).
[BP_RELATION:BY_CATEGORY:CHEEK:AROUND:BY_CATEGORY:TEETH:100]
[BP_RELATION:BY_CATEGORY:CHEEK:AROUND:BY_CATEGORY:MOUTH:100]
[BP_RELATION:BY_CATEGORY:CHEEK:AROUND:BY_CATEGORY:TONGUE:100]

Compared to .34.03:
[BODY_DETAIL_PLAN:STANDARD_HEAD_POSITIONS]
This command lets you assign a position within the parent to all bodyparts that fit in a group.
[BP_POSITION:BY_CATEGORY:NOSE:FRONT]
[BP_POSITION:BY_CATEGORY:LIP:FRONT]
[BP_POSITION:BY_CATEGORY:TONGUE:FRONT]
[BP_POSITION:BY_CATEGORY:MOUTH:FRONT]
[BP_POSITION:BY_CATEGORY:CHEEK:FRONT]
[BP_POSITION:BY_TOKEN:R_EAR:RIGHT]
[BP_POSITION:BY_TOKEN:L_EAR:LEFT]
This command lets you establish a relationship between bodyparts within their parent bodypart. The number establishes the extent to which the relationship holds (only used for bodyparts, not the tissue relationships above).

[BP_RELATION:BY_TOKEN:R_EYELID:AROUND:R_EYE:50]
[BP_RELATION:BY_TOKEN:L_EYELID:AROUND:L_EYE:50]
[BP_RELATION:BY_TOKEN:EYELID:AROUND:EYE:50]
[BP_RELATION:BY_TOKEN:R_EYELID:CLEANS:R_EYE:100]
[BP_RELATION:BY_TOKEN:L_EYELID:CLEANS:L_EYE:100]
[BP_RELATION:BY_TOKEN:EYELID:CLEANS:EYE:100]
Looks like the underscores were removed for R_EYE and L_EYE, is all. Should be a simple fix.
As for body_rcp, it looks like the following replaced the old [BODY:RCP_EYELIDS]:
[BODY:RCP_1_EYELID]
[BP:EYELID:eyelid:STP][CONTYPE:HEAD][CATEGORY:EYELID][SMALL][EMBEDDED]
[DEFAULT_RELSIZE:4]
[BODY:RCP_2_EYELIDS]
[BP:L_EYELID:left eyelid:STP][CONTYPE:HEAD][CATEGORY:EYELID][SMALL][EMBEDDED]
[DEFAULT_RELSIZE:2]
[BP:R_EYELID:right eyelid:STP][CONTYPE:HEAD][CATEGORY:EYELID][SMALL][EMBEDDED]
[DEFAULT_RELSIZE:2]
[BODY:RCP_3_EYELIDS]
[BP:L_EYELID:left eyelid:STP][CONTYPE:HEAD][CATEGORY:EYELID][SMALL][EMBEDDED]
[DEFAULT_RELSIZE:2]
[BP:R_EYELID:right eyelid:STP][CONTYPE:HEAD][CATEGORY:EYELID][SMALL][EMBEDDED]
[DEFAULT_RELSIZE:2]
[BP:EYELID:center eyelid:STP][CONTYPE:HEAD][CATEGORY:EYELID][SMALL][EMBEDDED]
[DEFAULT_RELSIZE:2]
Hope this helps! For all I know you might have already solved this by now, but I felt like I should give back to someone who's made something that I've spent a lot of time enjoying.
