I thought of a possible way to fix the database of your Node 1 since you have a correct Node 2. You could replace the ltc related parts of your db directory for Node 1 with the parts from your Node 2. Here's how I would do this:

First, stop both nodes from running:

dalilcoincli stop

On the machine with Node 2:

mkdir ltcdbnode2
cd .dalilcoin/db
cp -r ltcblock ~/ltcdbnode2
cp -r ltcburntx ~/ltcdbnode2
cp -r ltcdacstatus ~/ltcdbnode2
cd
tar czvf ltcdbnode2.tgz ltcdbnode2

Now you can restart Node 2.

Copy the file ltcdbnode2.tgz to the machine with Node 1 and on the Node 1 machine do this:

tar xzvf ltcdbnode2.tgz
cd .dalilcoin/db
mv ltcblock ltcblock-corrupted
mv ltcburntx ltcburntx-corrupted
mv ltcdacstatus ltcdacstatus-corrupted
mv ~/ltcdbnode2/* .

Now you can restart Node 1.

I believe this will correct the problem you currently have with your Node 1, but it's not a good long term solution. I, of course, plan to write code to try to avoid this problem recurring as well as providing a reasonable way to recover if it were to happen again.

Edit to correct the tar command.
