[BUG][PLAYER] Error message before the first skill assignment

[IchoTolot]

From IRC:

<Chaotix>o/
<Chaotix>I stumbled across an error message that shows up in the beginning of a level when you pause and click to move one frame forward
<Chaotix>Is that a known issue? I'll post a video in about 20 seconds which shows the message
<Chaotix>https://dl4.volafile.io/get/Zj6wPZrEOg-4/lem.webm
<Chaotix>At the 19 second mark
<IchoTolot>hm never seem that before
<Chaotix>http://puu.sh/nvZ2h/df19677e31.png My specs if they're relevant?
<IchoTolot>no crash though strage
<IchoTolot>strange
<Chaotix>That's what I was wondering about as well
<Chaotix>And it also only happened in this one stage so far
<Chaotix>Psycho 2 of Lemmings Plus I
<IchoTolot>so you pause  put the RR up da bit and then simply  1 frame forward
<IchoTolot>Yes i can reprodice it even in Lemmings reunion!
<Chaotix>Yep. It also happens when I start a level, pause immediatly, change RR (before "Let's Go!") and click one frame forward
<IchoTolot>It's   start the level ----- pause before let's go ------ put the RR up a bit ----- try to 1 frame forward
<Chaotix>Yep
<Chaotix>But in the video it also happened after let's go
<Chaotix>For the first time, but that could have been caused by OBS maybe?
<IchoTolot>wait I'll check it a bit more precisely
<Chaotix>So you can reproduce it, right?
<Chaotix>Anyway, I just wanted to let you know. I gotta leave again, but I'll be back later. Good day everyone!
- Chaotix quit (Signed off)
<IchoTolot>even 16 secs in this is reproducable!
<IchoTolot>and FF and a Lem that dies is also not stopping this error
<IchoTolot>namida42 we've got a situation here!
<IchoTolot>just assigning seems to stop it
<IchoTolot>30 secs into a level with (FF on/off) doing nothing  --- then pause ---- RR increasing ----- 1 frame forward ---- error
<IchoTolot>1 assign and the error does not accur
<IchoTolot>if all Lems are out doesnt matter
<IchoTolot>omg I created a million errors     just by using the 10 secs skip instead of the 1 frame forward    seems like 1 error foe each skipped frame forward

So again to redproduce the error:

1.) Go into a level and do nothing for as long as you like (FF and skipping forward/backwards is allowed!)
2.) Pause
3.) Turn the RR up a bit.
4.) Skip forward and you'll get to recieve 1 error message for each frame you wanted to skip forward (1 frame forward = 1 error; 10 secs = a bazillion errors   but again no crash!) 
Task manager if you've created too many.

EDIT: Changing the skill in the skillbar seems to also avoid the error.

Very strange indeed. I'll be able to look into it later today, and since this is quite major, I'll release a V1.43n-D update as soon as I manage to find a fix.

Found the cause of this and made a fix. Uploading now.
